What Are Crib Booties with Built-In White Noise Soothers?
Crib booties represent the convergence of nursery safety padding and portable sound therapy. These fabric sleeves fit over crib rails or slats, housing a slim, integrated speaker system that emits continuous, non-looping white noise or other soothing sounds. The design philosophy centers on creating a contained auditory environment that travels with your baby, whether they’re at home, in a hotel, or at grandma’s house.
The Evolution from Traditional Sleep Aids
Traditional white noise machines have served families for decades, but they come with inherent limitations. Positioning becomes a constant calculus—too close and you risk hearing damage; too far and the sound loses its masking effectiveness. Crib booties eliminate this guesswork by embedding the sound source directly into the crib’s architecture. This evolution mirrors our broader understanding of infant safety: just as we moved from loose crib bumpers to mesh alternatives and from drop-side cribs to fixed rails, we’re now reimagining sleep technology to be inherently integrated rather than peripherally placed.
How Integrated Technology Works
The engineering behind these devices is surprisingly sophisticated. Micro-speakers, often no thicker than a few millimeters, are woven into padded fabric channels that wrap securely around crib rails. These speakers connect to a control unit—typically housed in a waterproof, chew-resistant pod—that manages power, volume, and sound selection. Advanced models utilize waveguide technology to distribute sound evenly along the crib’s perimeter, creating a cocoon of consistent audio rather than a directional blast from a single point. This omnidirectional approach prevents your baby from developing a sound “hotspot” preference that could lead to positional head-turning.
The Science Behind White Noise and Infant Sleep
Understanding why these devices work requires diving into neonatal neurology and the physics of sound masking. Babies spend nine months in an environment far louder than most parents realize—the womb registers at approximately 75-92 decibels, comparable to a vacuum cleaner. That constant whooshing of blood flow and maternal bodily functions becomes a deeply ingrained comfort signal.
Understanding the Auditory Environment in the Womb
The fetal auditory experience isn’t quiet tranquility—it’s a rich tapestry of low-frequency rumblings and rhythmic whooshing. When newborns enter the comparatively silent outside world, the absence of this constant sound can actually be unsettling. White noise booties replicate the spectral qualities of intrauterine sound: heavy on low frequencies, continuous, and predictable. This isn’t just comforting nostalgia; it activates the vestibular system in ways that promote sleep onset and maintenance. Research suggests that infants exposed to womb-like sound patterns show reduced cortisol levels and more organized sleep architecture.
Why Consistent Sound Matters for Sleep Cycles
Infant sleep cycles last roughly 45-50 minutes, and the transition between cycles is where most naps fall apart. During these vulnerable moments, environmental consistency becomes crucial. A sudden silence—when a traditional white noise machine shuts off—or an abrupt noise from another room can trigger full arousal. Integrated booties provide seamless sound continuity that bridges these cycle gaps. The key lies in the “sound wall” concept: consistent background noise raises the auditory threshold, meaning your baby sleeps through sounds that would otherwise wake them. It’s not about drowning out noise with volume; it’s about creating a stable acoustic baseline.
Key Benefits for Naptime Success
While nighttime sleep often gets the spotlight, daytime naps present unique challenges. Household activity peaks, older siblings are home, and environmental control becomes more complex. Crib booties address these nap-specific hurdles with targeted benefits.
Creating Portable Sleep Associations
Sleep associations can be powerful tools or frustrating crutches, depending on their portability. A baby who associates sleep with the exact white noise machine in their nursery struggles to nap elsewhere. Booties solve this by becoming part of the crib itself—whether it’s your home crib, a pack-and-play, or a travel crib. The visual and tactile presence of the padded rail, combined with the familiar sound, creates a multisensory sleep cue that travels with your baby. This portability becomes invaluable during the first year when families average seven different sleep locations due to travel, daycare transitions, and visits to relatives.
Extending Short Naps Naturally
The dreaded 30-minute nap plagues many parents, and it’s often triggered by cycle transitions coinciding with environmental noise. A bootie’s continuous sound can extend these naps by smoothing the transition between sleep cycles. Many parents report naps lengthening by 40-60% after consistent use. The mechanism isn’t magical—it’s simply reducing micro-arousals that accumulate over a nap period. When your baby isn’t constantly adjusting to new sounds, they can progress through deeper sleep stages and complete full cycles more efficiently.
Reducing Sleep Disruptions from Household Noise
Daytime life doesn’t pause for naps. Dishwashers run, doorbells ring, siblings play. Traditional sound machines placed across the room struggle to mask these proximal sounds effectively. Booties, positioned inches from your baby’s head, create a localized sound field that more effectively masks nearby disturbances. The physics are straightforward: sound intensity decreases with distance. A bootie’s proximity means it can operate at safer, lower volumes while achieving better masking than a distant machine cranked to high levels.
Critical Safety Features to Prioritize
When technology meets infant sleep products, safety scrutiny must intensify. These devices introduce electronic components into the immediate sleep environment, requiring rigorous safety engineering.
Material Certifications and Breathability Standards
The fabric components should meet or exceed crib textile standards: OEKO-TEX Standard 100 certification ensures no harmful substances, while GOTS certification guarantees organic fiber integrity. More importantly, breathability testing becomes critical since these products sit against crib rails where faces might press. Look for materials with air permeability ratings exceeding 300 mm/s, similar to mesh crib liner standards. The padding should be firm enough to prevent contouring around faces but soft enough to protect against bumps. Avoid any product using memory foam, which can create dangerous air pockets.
Secure Attachment Without Entanglement Risks
Attachment mechanisms must be robust yet simple. Velcro closures should be industrial-grade with no loose threads, while snap systems need breakaway force testing to ensure they release under pressure rather than creating a strangulation loop. The ideal system uses multiple small attachment points rather than one long continuous strip, distributing force and preventing the entire bootie from becoming a single hazard. All fasteners should be recessed or covered when closed, with no exposed plastic hardware that could detach and become a choking hazard.
Volume Limiting Technology and Hearing Protection
This feature is non-negotiable. Pediatric audiologists recommend keeping white noise below 50 decibels at the infant’s ear level. Quality booties incorporate hard-wired volume limiters that cannot be overridden, capping output at safe levels even if the parent accidentally sets controls too high. Some advanced models include proximity sensors that automatically adjust volume based on how close your baby’s head is to the speaker. Always verify that volume controls require a deliberate, multi-step process to increase—no simple dial that a curious toddler could twist.
Sound Quality and Customization Options
Not all white noise is created equal, and infant preferences vary dramatically. The best booties offer sophisticated audio engineering that goes beyond a simple static hiss.
Decoding White Noise Variations: Pink, Brown, and Beyond
White noise contains equal energy across all frequencies, which can sound harsh to sensitive ears. Pink noise reduces energy as frequency increases, creating a deeper, more natural sound—like steady rainfall. Brown noise (or Brownian noise) emphasizes even lower frequencies, resembling distant thunder or strong wind. Many babies show clear preferences, with studies suggesting pink noise correlates with deeper sleep stages. Premium booties offer multiple color noises, allowing you to experiment and find what resonates with your baby’s neurological wiring.
Adjustable Tone, Pitch, and Frequency Settings
Beyond pre-set noises, advanced models let you fine-tune the sound signature. This matters because household noises you need to mask have specific frequency profiles. A high-pitched dog bark requires different masking than a low-frequency washing machine rumble. Tone controls let you emphasize frequencies that counter your specific home’s noise signature. Some units even include a “sound profiling” feature where you record your environment, and the device creates a customized masking profile.
Looping Quality and Audio Fidelity
Poorly engineered sound loops create detectable patterns that can actually stimulate rather than soothe. Look for booties advertising “seamless looping” with loops lasting several hours or using generative algorithms that create truly non-repeating soundscapes. Audio fidelity matters too—distorted, crackly speakers produce harsh harmonics that irritate developing auditory systems. The speaker should have a frequency response covering at least 100-8,000 Hz, with minimal total harmonic distortion (THD under 1%).
Power and Battery Considerations
Nothing derails a nap faster than a dead battery mid-cycle. Understanding power management separates reliable booties from frustrating gadgets.
Rechargeable vs. Replaceable Battery Systems
Rechargeable lithium-ion batteries offer convenience and cost savings but raise concerns about long-term capacity degradation. Replaceable AA or AAA batteries provide backup simplicity but create ongoing expense and environmental waste. Hybrid systems represent the best of both worlds: rechargeable with a backup battery compartment for emergencies. Consider your usage pattern—daily naps at home favor rechargeables, while frequent travel might benefit from replaceables you can swap anywhere.
Battery Life Expectations for Daily Use
Real-world battery life rarely matches manufacturer claims, which are often measured at low volume in ideal conditions. For naptime use (1-3 hours daily), expect quality rechargeable units to last 5-7 days between charges. Continuous nighttime use might require daily charging. Pay attention to standby power consumption—some units drain significantly even when not actively playing sound. Look for models with physical on/off switches rather than soft switches that maintain standby current.
Low-Battery Indicators and Fail-Safe Features
Sudden silence can be more disruptive than no white noise at all. Premium booties include gradual volume fade-outs when batteries deplete, preventing abrupt wake-ups. Visual low-battery indicators should be discreet—no bright LEDs that could stimulate your baby—but obvious enough for parents to notice during routine checks. The best systems send smartphone notifications when power drops below 20%, giving you time to recharge before the next nap.
Smart Technology Integration
Modern parenting increasingly relies on connected devices, but smart features must enhance rather than complicate the sleep experience.
Bluetooth Connectivity and App Controls
App-based controls allow you to adjust settings without entering the nursery—a godsend during those “baby just fell asleep” moments. However, connectivity should never be the only control method; physical buttons on the device itself are essential for grandparents or caregivers without the app. The Bluetooth range needs to penetrate walls reliably—look for Bluetooth 5.0 or higher with at least 100-foot range. Critical safety note: the bootie must function independently if the connection drops; no dependency on continuous signal.
Timer Functions and Gradual Fade-Out Features
While continuous sound works best for newborns, older babies benefit from timers that teach self-soothing. Look for customizable fade-out periods ranging from 10 minutes to 2 hours, with volume decreasing so gradually it’s imperceptible. Some advanced models sync fade-out with your baby’s detected sleep cycle, using accelerometer data to determine optimal shutoff timing. This prevents the jarring silence that can occur if a timer cuts out during light sleep.
Firmware Updates and Feature Expansions
Sound technology evolves, and your bootie should too. USB-updatable firmware ensures your device improves over time with new sound libraries or refined algorithms. However, updates should never happen automatically during sleep times. The best systems schedule updates for when the unit is charging and inactive, with manual override options for parents who prefer to wait.
Proper Placement and Installation Techniques
Even the most sophisticated bootie underperforms if positioned incorrectly. Installation affects both safety and acoustic effectiveness.
Optimal Positioning for Sound Distribution
Mount booties at crib rail height, roughly level with your baby’s ears when lying down. This creates a direct sound path without requiring high volume. For cribs with four rails, position booties on the side rails rather than the headboard or footboard—this creates a stereo field that envelops rather than blasts. Avoid placing them directly against the wall; a 2-3 inch gap allows sound to diffuse naturally. If your crib sits in a corner, prioritize the rail facing the noisiest room area.
Ensuring Secure Attachment to Crib Rails
Follow the manufacturer’s weight distribution guidelines—most specify maximum speaker unit placement to prevent sagging. Test the attachment by giving a firm tug; it shouldn’t shift or gap. Check daily for loosening, especially after washing. For adjustable-height cribs, position booties at the highest setting you’ll use; moving them up and down repeatedly weakens fasteners. Never attach additional items to the bootie, and ensure no gaps exist between the bootie and rail where tiny fingers could get trapped.
Adjusting for Different Crib Styles and Sizes
Convertible cribs with wide rails may require extension straps or larger bootie sizes. Round or unusually shaped rails need booties with flexible internal frames that conform without creating pressure points. For mini cribs or pack-and-plays, look for travel-specific models with slimmer profiles. Measure your crib rails before purchasing—most booties accommodate rails 1-3 inches wide, but oversized nursery furniture may need custom solutions.
Age-Appropriate Usage Guidelines
One size doesn’t fit all when it comes to infant development. Bootie usage should evolve with your baby’s changing needs and abilities.
Newborn Considerations and Gentle Introduction
For babies under three months, start with the lowest volume setting and the most womb-like sound (deep pink or brown noise). Newborns have sensitive hearing and are still adjusting to the external world. Use booties only during initial sleep onset for the first week, gradually extending to full nap duration. Monitor for signs of overstimulation: increased startle reflexes, difficulty settling, or unusual fussiness when the sound activates. Some newborns prefer silence; respect these individual differences rather than forcing sound exposure.
Transitioning as Your Baby Grows
Between 4-6 months, babies become more aware of their environment. This is the ideal window to establish consistent bootie use if you haven’t already. At this stage, introduce subtle variations in sound to prevent rigid associations—alternate between two similar pink noise profiles. Around 8-10 months, when separation anxiety peaks, the familiar bootie sound becomes a powerful comfort object. However, this is also when babies start pulling to stand; ensure booties remain securely attached as your baby uses rails for support.
When to Phase Out White Noise Dependency
Most pediatric sleep experts recommend beginning weaning around 12-18 months. Start by lowering volume 5% weekly using app controls or gradual adjustment features. Alternatively, use timer functions to have sound fade out earlier in the nap, allowing your baby to complete final sleep cycles in silence. Some families continue low-level background noise indefinitely without issue—the key is ensuring your child can sleep without it when necessary, such as during daycare or travel where the bootie isn’t available.
Maintenance and Hygiene Best Practices
Sleep accessories demand rigorous cleanliness standards, but electronics complicate traditional washing methods.
Cleaning Fabric Components Safely
Always remove electronic modules before washing. Most bootie fabrics are machine-washable but require specific care: use fragrance-free detergent, cold water, and gentle cycles to preserve water-resistant coatings. Avoid fabric softeners, which can degrade flame retardants and create residue that irritates sensitive skin. Air dry completely before reinserting electronics—residual moisture can cause corrosion. For spot cleaning, use a damp cloth with mild soap; never spray cleaners directly onto the fabric as liquid can seep into speaker grilles.
Sanitizing Electronic Elements
The control pod and speaker housings need regular sanitizing, especially during cold season. Use 70% isopropyl alcohol wipes on exterior surfaces only—never submerge or spray electronics. Pay attention to button crevices and charging ports where germs accumulate. For deeper cleaning, some manufacturers offer UV sanitizing cases. Check warranty terms before using any sanitizing method; some void coverage if moisture indicators are triggered. Monthly, inspect speaker grilles for dust buildup, using a soft brush to clear debris that muffles sound quality.
Storage Between Uses
If you rotate booties between locations or seasons, store them in breathable cotton bags—not plastic, which traps moisture. Remove batteries from replaceable units to prevent corrosion. For rechargeable models, store at 50% charge; full charges degrade lithium batteries over time, while complete discharge can make them unrecoverable. Every three months during storage, give them a brief charge cycle to maintain battery health. Keep in a cool, dry place away from direct sunlight, which can fade fabrics and warp plastic components.
Common Concerns and Misconceptions
Despite growing popularity, these devices generate valid concerns among parents and pediatric professionals. Addressing these head-on helps make informed decisions.
The Independence Debate: Creating Healthy Sleep Habits
Critics argue that external sleep props prevent babies from learning self-soothing. However, research distinguishes between positive sleep associations (consistent environments) and negative ones (requiring parental intervention). White noise booties function like blackout curtains or comfortable pajamas—they create optimal conditions without requiring your presence. The key is consistency: use the bootie for all sleeps to make the sound part of the baseline environment, not a special crutch. Avoid using it sporadically as a “rescue” tool, which teaches dependency on crisis intervention rather than environmental stability.
Addressing Potential Overstimulation
While some babies thrive with background noise, others become sensitized. Watch for warning signs: fighting sleep when the bootie activates, increased agitation during sound playback, or regression in sleep quality after initial improvement. If you suspect overstimulation, try switching to brown noise (lower frequencies are less activating) or reducing volume by 30%. Some babies need a “sound break” period—try naps without the bootie every third day to assess baseline sleep quality. Trust your parental observation; no device replaces your understanding of your baby’s unique temperament.
Volume Level Myths and Facts
Many parents mistakenly believe louder masking is better. In reality, the goal is to raise the background threshold just enough to obscure unpredictable noises, not to create a loud environment. The “just noticeable difference” principle applies: sound only needs to be 3-5 decibels above ambient noise to be effective. Louder volumes don’t improve masking and may cause auditory fatigue. Follow the pediatric guideline of 50 dB maximum, but aim for 40-45 dB for routine use. Use a free sound level meter app to measure at mattress level, not at the bootie itself.
Cost Analysis and Value Proposition
These specialized devices command premium pricing compared to basic white noise machines. Understanding the value equation helps justify the investment.
Price Range Expectations
Quality booties typically range from $75 to $180, with smart features pushing toward the higher end. Budget options under $50 often compromise on speaker quality, battery life, or safety certifications. Consider cost-per-use: if your baby naps 500 times in the first year, a $150 bootie costs $0.30 per nap. Compare this to the value of those extra sleep hours for your baby’s development and your sanity. Avoid ultra-cheap imports lacking FCC or CE certification; unregulated electronics near infants pose fire and toxicity risks that far outweigh initial savings.
Longevity and Durability Factors
A well-made bootie should function reliably for 2-3 years, serving multiple children. Evaluate construction quality: reinforced stitching at stress points, water-resistant control pods, and speaker grilles that resist poking fingers. Check warranty terms—reputable manufacturers offer at least one year, with some extending to two years for electronic components. Replacement policies matter too; can you purchase individual parts like speakers or battery packs, or must you replace the entire unit? Modular designs offer better long-term value.
Warranty and Customer Support Considerations
Beyond duration, examine warranty coverage specifics. Does it include water damage from cleaning? What about battery degradation? The best companies offer dedicated parent support lines with sleep consultants who understand their product’s nuances. Read customer service reviews carefully—companies that respond promptly to safety concerns demonstrate accountability. Some offer trial periods (30-90 days) with full refunds if the bootie doesn’t suit your baby, which is invaluable given individual variability in sound preference.
Integration with Your Existing Sleep Routine
Booties work best as part of a comprehensive sleep system, not as standalone solutions. Thoughtful integration maximizes benefits.
Combining with Swaddles and Sleep Sacks
The bootie’s sound complements the tactile security of swaddles and sleep sacks. For newborns, the combination recreates womb conditions remarkably well: snug pressure plus familiar noise. As babies transition out of swaddles around 3-4 months, the consistent bootie sound provides continuity during this adjustment period. Ensure the bootie doesn’t interfere with safe swaddle placement—rails should remain accessible for emergency access, and the bootie shouldn’t create gaps where fabric could bunch near the face.
Coordinating with Room Environment Controls
White noise booties don’t replace optimal room conditions; they enhance them. Maintain room temperature between 68-72°F and use blackout curtains. The bootie should be the final layer, not the foundation. Consider your HVAC system—if it cycles noisily, the bootie masks this inconsistency. For rooms with unavoidable light or activity, the bootie’s sound helps create a sensory “bubble” that isolates your baby from stimulation. Some parents pair booties with gentle crib vibration pads, but introduce these elements sequentially to identify what truly helps versus overwhelms.
Establishing Consistent Pre-Nap Rituals
Use the bootie’s activation as a clear sleep cue. Develop a ritual: close curtains, change diaper, put on sleep sack, activate bootie sound, then place baby in crib. This sequence creates predictable associations. Avoid turning on the bootie while your baby is already upset; the sound should signal calm readiness, not desperation. Some parents find that activating the bootie 2-3 minutes before placing the baby in the crib allows the sound environment to establish itself, making the transition smoother.
Troubleshooting Typical Issues
Even premium booties encounter problems. Knowing common failure modes helps you address issues quickly.
Sound Quality Degradation Over Time
Speakers can develop crackling or volume drops after months of use. This often results from dust accumulation or moisture exposure. First, clean speaker grilles thoroughly. If problems persist, contact the manufacturer—reputable brands replace speakers under warranty. Some degradation is normal after 12-18 months of continuous use; speaker diaphragms fatigue over time. Keep firmware updated, as some audio issues stem from software glitches rather than hardware failure. If sound becomes tinny or distorted, check battery voltage—low power can cause clipping and poor amplifier performance.
Attachment Problems with Modern Crib Designs
Today’s cribs feature diverse rail profiles: tapered, curved, or extra-wide designs. If booties slip or gap, use manufacturer-provided adapter straps or shim kits. Never use your own materials to modify attachment, as this voids safety certifications. For cribs with teething rails (plastic covers), remove these first—booties attach directly to wood/metal. Some parents find that booties work better on the vertical slats rather than horizontal rails of certain crib styles. If persistent attachment issues occur, the bootie may not be compatible with your crib model; return it rather than forcing a suboptimal fit.
Connectivity and App-Related Glitches
Smart booties occasionally drop connections or freeze. First, ensure your phone’s Bluetooth isn’t competing with multiple devices. Force-close and restart the app, then power-cycle the bootie (full shutdown, wait 30 seconds, restart). If issues continue, check for firmware updates—these often fix connectivity bugs. For persistent problems, disable smart features and use manual controls; a reliably functioning basic bootie beats a glitchy smart one. Some families keep a cheap backup white noise machine as insurance during app troubleshooting or when updates go wrong.
Frequently Asked Questions
How loud should I set the white noise in crib booties? Aim for 40-50 decibels measured at mattress level, roughly the volume of a soft shower. Use a free sound level meter app on your phone, placing it where your baby’s head rests. Start at the lowest effective volume and increase only if household noises still disrupt sleep. Never exceed 50 dB, as prolonged exposure above this level may affect developing hearing.
Can my baby become dependent on white noise booties for sleep? Babies can develop preferences for consistent sleep environments, but this differs from unhealthy dependency. The key is consistent use from the start rather than sporadic deployment. To prevent rigid associations, occasionally have your baby nap without the bootie (every 3-4 naps) to maintain flexibility. Most children naturally wean from white noise needs between 12-18 months as their sleep architecture matures.
Are crib booties with white noise safe for newborns? Yes, when they meet strict safety standards: volume limiting to 50 dB, secure attachment without loose parts, and breathable, certified fabrics. Introduce gradually, starting with the lowest volume and monitoring for overstimulation signs. Always follow manufacturer age recommendations—some booties are designed specifically for babies over 3 months due to speaker proximity and newborn ear sensitivity.
How do I clean the booties without damaging the electronics? Remove all electronic modules before washing. Most fabric covers are machine-washable in cold water with fragrance-free detergent. Air dry completely before reassembly. Clean electronic pods with 70% isopropyl alcohol wipes on exterior surfaces only. Never submerge speakers or control units. Check manufacturer instructions—some require hand-washing to maintain water-resistant coatings.
Will the booties fit my convertible crib with wide rails? Most booties accommodate rails 1-3 inches wide. Measure your crib rails before purchasing. For oversized rails (3+ inches), look for booties with extension straps or “XL” sizing. Some manufacturers offer adapter kits for specific crib brands. Avoid forcing standard booties onto wide rails, as improper fit creates gaps that pose entanglement risks.
How long do batteries typically last in white noise booties? Rechargeable models last 5-7 days with 1-3 hours of daily nap use. Continuous nighttime use may require charging every 1-2 days. Replaceable battery units typically run 20-30 hours on a fresh set. Battery life decreases over time; expect 20% reduction after 12 months of regular use. Always keep a backup power solution for critical nap times.
Can I use the booties for nighttime sleep or just naps? Most booties are designed for both nap and nighttime use, though some parents prefer dedicated devices for overnight. The key consideration is battery life—ensure the unit can run 10-12 hours continuously if used all night. Some models have different sound profiles optimized for deep nighttime sleep versus shorter nap cycles. Check warranty terms, as continuous use may affect coverage duration.
What’s the difference between white, pink, and brown noise settings? White noise has equal energy across all frequencies, sounding like static. Pink noise reduces high-frequency energy, creating a deeper, more natural sound (like steady rain). Brown noise emphasizes low frequencies, resembling distant thunder. Babies often prefer pink or brown noise as they’re closer to womb sounds. Experiment to find which your baby responds to best—there’s no universal “right” choice.
Do smart booties work without WiFi or when Bluetooth disconnects? Quality smart booties function independently without constant connectivity. Bluetooth is used for initial setup and adjustments, but the device stores settings locally. If your phone disconnects or WiFi fails, the bootie continues playing the last selected sound at the set volume. Avoid models that require continuous app connection or cloud access—these create unacceptable failure points in critical sleep situations.
How do I know if the bootie is positioned correctly on the crib? Position booties at mattress level, aligned with where your baby’s ears rest when lying down. They should feel snug on the rail with no gaps or sagging. Test by gently pulling—secure attachment shouldn’t shift. Sound should distribute evenly; if you hear obvious “hot spots” or distortion, reposition. Check that no part of the bootie extends into the crib interior where your baby could reach it. When in doubt, consult manufacturer installation videos for your specific crib type.
