Safe Sleep Starts with the ABCs

The single most important thing you can do for your baby’s sleep safety is follow the ABCs: Alone, on their Back, in a Crib. This simple rule dramatically reduces the risk of Sudden Infant Death Syndrome (SIDS) and accidental suffocation. Place your baby on a firm, flat mattress with a fitted sheet, and nothing else in the crib. No blankets, pillows, bumper pads, stuffed animals, or positioners. If you’re worried about your baby getting cold, use a wearable blanket or sleep sack.

Room-Sharing is Recommended, Bed-Sharing is Not

Experts recommend room-sharing (keeping your baby’s crib or bassinet in your room) for at least the first six months, ideally the first year. This arrangement can reduce the risk of SIDS by up to 50% and makes nighttime feedings easier. However, bed-sharing (sleeping on the same surface as your baby) is not recommended. The adult bed has risks: soft mattresses, pillows, and blankets can lead to suffocation, and there’s a risk of rolling onto your baby. If you fall asleep accidentally while feeding, return your baby to their own sleep space as soon as you wake up.

The Right Sleep Surface and Environment

Always place your baby to sleep on a firm, flat, safety-approved crib, bassinet, or play yard mattress. Avoid inclined sleepers, swings, or car seats for routine sleep, as they can cause your baby’s head to fall forward, restricting breathing. Keep the room at a comfortable temperature (68-72°F or 20-22°C) and dress your baby in one extra layer than you’d wear. Signs of overheating include sweating or a warm chest. Offer a pacifier at naptime and bedtime (if breastfeeding, wait until breastfeeding is well-established, usually around 3-4 weeks). No need to reinsert it if it falls out after they’re asleep.

What About Products That Claim to Reduce SIDS?

You may see products like sleep positioners, wedges, or special mattresses marketed to reduce SIDS. Do not use them. They have not been proven safe or effective, and can actually increase the risk of suffocation. Similarly, cardiorespiratory monitors or wearable devices are not recommended for healthy babies to prevent SIDS. They can give false reassurance and have not been shown to reduce SIDS. The safest sleep environment is simple: a firm mattress, tight-fitting sheet, and nothing else.

Transitioning from Swaddle to Sleep Sack

If you swaddle your newborn, stop swaddling once they show signs of rolling over (usually around 2-3 months). A swaddled baby who rolls to their tummy can suffocate. Transition to a sleep sack or wearable blanket. Make sure the sleep sack fits properly (neck and armholes snug, not too loose). Always place your baby on their back to sleep, even after they start rolling. Once they can roll both ways consistently, you can let them find their own position, but always start them on their back.

When to Call Your Pediatrician

Safe sleep guidelines are important, but every baby is different. If your baby has a medical condition that might affect sleep position (like reflux, a breathing issue, or a birth defect), talk to your pediatrician about any adjustments. Also, if your baby seems unusually sleepy, has trouble breathing, or you have any concerns about their sleep safety, don’t hesitate to call your pediatrician. They’re there to help you navigate your baby’s unique needs.

Key Takeaway

Always place your baby on their back, on a firm, flat mattress, with no loose bedding, toys, or pillows, and room-share but never bed-share.
