Knowledge is the most powerful tool a parent can have. Here you'll find evidence-based information about SIDS and safe sleep, and an honest note on what a wellness band like Bundl can and can't do.
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.
No monitor or wearable can prevent SIDS, and Bundl never claims to. The American Academy of Pediatrics advises against using home monitors as a way to reduce SIDS risk; safe sleep practices are what protect babies. Bundl's role is smaller and calmer: helping you understand your baby's patterns, and supporting you and the habits above.
The Bundl charging dock reads room temperature and humidity, making it easier to keep the nursery comfortable and avoid overheating, one of the safe sleep factors above.
How much your baby slept, how often they woke, and the longest stretch, next to what's typical for their age, so ordinary night waking feels less worrying.
A visit-ready report of your baby's patterns and your questions, so well-baby visits, where safe sleep is always a good topic, go further.
Exhaustion makes safe sleep harder, especially at 3am. After hard nights, Bundl checks in on you with practical ideas, like trading a protected stretch of sleep, and support that's always there.
Bundl does not monitor blood oxygen, does not send medical alerts or alarms, and is not intended to diagnose, treat, cure, or prevent any disease or condition, including SIDS. It has not been evaluated by the FDA. Always follow safe sleep guidelines, talk to your pediatrician with any concerns, and call 911 in an emergency.
