Knowledge is the most powerful tool a parent can have. Here you'll find evidence-based information about SIDS, safe sleep practices, and how continuous monitoring can support informed care.
Understanding risk factors can help parents make informed decisions. Many risk factors are modifiable, meaning you can take steps to reduce them.
Risk is highest between 1 and 4 months of age. About 90% of SIDS deaths occur in the first 6 months of life. The risk decreases significantly after 6 months.
Stomach sleeping increases risk significantly. Side sleeping is also riskier than back sleeping. Always place babies on their backs to sleep until age 1.
Prenatal or postnatal exposure to cigarette smoke significantly increases SIDS risk. This includes secondhand smoke exposure in the home environment.
Babies who become too hot during sleep face elevated risk. Overdressing, heavy blankets, and warm room temperatures are contributing factors.
Premature birth, low birth weight, multiple birth (twins, triplets), and inadequate prenatal care are associated with higher SIDS risk.
Soft bedding, pillows, bumper pads, loose objects in the crib, and bed-sharing on soft surfaces all increase risk. A firm, flat surface is safest.
The American Academy of Pediatrics (AAP) recommends these evidence-based safe sleep practices. Together, they represent the most effective risk-reduction strategy available.
Always place your baby on their back to sleep, for naps and at night, until their first birthday. Even if baby can roll over, start them on their back.
Use a firm, flat sleep surface such as a safety-approved crib, bassinet, or play yard with a tight-fitting sheet. Avoid inclined sleepers and positioners.
Share your room (ideally for at least 6 months) but on a separate sleep surface. Room-sharing reduces SIDS risk by up to 50% without the risks of bed-sharing.
No pillows, blankets, bumper pads, soft toys, or positioners in the sleep space. A wearable blanket (sleep sack) is a safe alternative to loose blankets.
Do not smoke during pregnancy or allow smoking near your baby. Avoid alcohol and sedating medications when you will be sharing a sleep space with your baby.
Breastfeeding, even for a short time, can reduce SIDS risk by up to 50%. The protective effect is stronger with exclusive breastfeeding for at least 2 months.
Offering a pacifier at sleep time reduces SIDS risk. If breastfeeding, wait until 3–4 weeks. Don't force it; if baby doesn't want it, that's okay.
Evidence shows that vaccinations are protective against SIDS, reducing risk by about 50%. Vaccines do not cause SIDS, a thoroughly debunked myth.
No commercial device, including home monitors, has been proven to prevent SIDS. The AAP does not recommend these products as SIDS prevention tools.
Bundl does not prevent SIDS. No consumer device can. But Bundl helps parents stay aware, informed, and connected to their baby's wellbeing so you can respond quickly when something doesn't seem right.
Tracks heart rate through the night, giving you real-time insight and alerting you when readings drift outside normal ranges for your baby's age.
Monitors blood oxygen levels continuously. Low SpO₂ alerts can indicate breathing changes that may warrant attention. Always confirm with your pediatrician.
Continuous skin temperature monitoring helps you detect overheating trends early, one of the modifiable SIDS risk factors, before they become concerning.
Detects when baby is still for extended periods or shows unusual movement patterns, prompting parents to check in. Not a substitute for in-person supervision.
Tracks sleep phases, wake events, and total sleep duration over time, giving you data to share with your pediatrician at well-baby visits.
Generates trend reports you can share with your baby's doctor. More data means more informed conversations and better care, with no guesswork at appointments.
Bundl has not been evaluated by the FDA and is not intended to diagnose, treat, cure, or prevent any disease or condition, including SIDS. Alert thresholds are informational and should not be used as the sole basis for medical decisions. Always consult your pediatrician or call 911 in an emergency.
