When you bring a newborn home from the hospital, safe sleep information comes at you from every direction: discharge paperwork, nurses, pediatricians, well-meaning relatives, and a dozen different apps. Some of it is clear. Some of it feels contradictory. And some of it is genuinely difficult to follow at 3 a.m. when you are running on 90 minutes of sleep and your baby has been awake for two hours.
This guide covers the AAP Safe Sleep 7 in plain language — what each recommendation is, why it matters, and how to actually implement it in a real household with real constraints. No judgment, no oversimplification. Just the information you need to keep your baby as safe as possible.
Rule 1: Back to Sleep for Every Sleep
Place your baby on their back for every sleep — naps, nighttime, every time — until their first birthday. The "back to sleep" campaign, launched in 1994 by the AAP and NICHD, reduced SIDS deaths in the United States by more than 50% in the decade following its introduction. That is not a modest effect. It is one of the most impactful public health interventions in recent pediatric history.
Why does back sleeping matter? When a baby sleeps face-down, they are more likely to rebreathe exhaled carbon dioxide, particularly if the sleep surface is soft enough to create a pocket around the face. The supine (back) position keeps the airway clear and allows the baby to arouse more easily from deep sleep if oxygen levels drop.
Once your baby can roll both directions independently (typically around 4 to 6 months), you no longer need to reposition them if they roll during sleep. But always start sleep on the back.
Rule 2: Firm, Flat Sleep Surface
Your baby must sleep on a firm, flat surface. "Firm" means the surface does not compress when you press on it with your palm — your handprint should not remain. "Flat" means level, not inclined at any angle.
Approved sleep surfaces include: a crib, bassinet, or play yard that meets current CPSC safety standards, with a firm mattress and a single tight-fitted sheet. That is the entire list. The adult bed is not a safe sleep surface. The sofa is not a safe sleep surface. An infant swing, bouncer, or car seat is not a safe sleep surface for routine unsupervised sleep.
Inclined sleepers — products that position the baby at an angle — were linked to dozens of infant deaths and were recalled by the CPSC starting in 2019. Any product that angles your baby's sleep position is not AAP-compliant, regardless of how it is marketed.

Rule 3: No Soft Objects or Loose Bedding
The sleep space — inside the crib, bassinet, or play yard — should contain nothing except the firm mattress and a tight-fitted sheet. Nothing else. No pillows. No loose blankets. No bumper pads (including mesh bumpers). No positioners. No stuffed animals. No sleep wedges.
This is the rule that surprises most new parents, because decorative nursery imagery invariably shows cozy, softly furnished cribs with bumpers and pillows. That imagery is not AAP-compliant and those products pose genuine risk. Soft objects in the sleep space can obstruct the airway if a baby's face presses against them. The 2022 AAP guidelines specifically call for removal of all such items.
For warmth, use a sleep sack (wearable blanket) appropriate for the room temperature. For the first few months, a swaddle is appropriate — but only until the baby shows signs of rolling. See our sleep sack guide for TOG ratings and sizing.
Rule 4: Room Sharing Without Bed Sharing
The AAP recommends your baby sleep in your room — in their own separate sleep space — for at least the first 6 months and ideally for the first year. Room sharing without bed sharing reduces SIDS risk by up to 50% compared to sleeping in a separate room from the start.
The distinction between room sharing and bed sharing is critical. Room sharing means a bassinet, crib, or play yard in your bedroom. Bed sharing — the baby sleeping on the adult mattress with you — significantly increases SIDS risk, particularly when combined with soft adult bedding, parental smoking, alcohol use, or exhaustion-related deep sleep.
A bedside bassinet is the most practical product solution for room sharing in the first 4 to 6 months. It keeps the baby at arm's reach without bringing them onto the adult bed.

Rule 5: Smoke-Free Environment
Smoking during pregnancy and exposure to secondhand smoke after birth are both significant independent risk factors for SIDS. The AAP recommends avoiding all tobacco smoke exposure — not just avoiding smoking in the same room, but avoiding situations where smoke residue (thirdhand smoke) is present on surfaces and clothing.
If anyone in the household smokes, do so outside and change clothing before holding or caring for the infant. Smoke exposure in the car — even windows-down — deposits residue on car seats and upholstery that infants are exposed to during transport.
Rule 6: Avoid Alcohol and Sedating Substances
The AAP includes avoiding alcohol and sedating medications as a safe sleep factor because these substances significantly increase the risk of accidental overlay and suffocation during any bed-sharing situation, even unintended ones. Exhausted parents who fall asleep while feeding in bed are at much higher risk of rolling onto the baby when alcohol or sedating drugs (including some antihistamines and prescription sleep aids) are involved.
If you are feeding your baby in bed and there is any chance you might fall asleep, set up a plan to move the baby to their safe sleep surface before you do. Falling asleep while feeding happens — having a plan in advance reduces the risk.
Rule 7: Consider a Pacifier at Sleep Time
Offering a pacifier at nap time and bedtime is associated with reduced SIDS risk. The mechanism is not fully established, but theories include maintained airway patency and increased arousal sensitivity. The AAP recommends offering a pacifier once breastfeeding is established (typically 3 to 4 weeks). If the baby refuses, do not force it. Never attach the pacifier to a clip, string, or stuffed animal in the sleep space.
Swaddles and Sleep Sacks: Where They Fit in Safe Sleep
Swaddling is a traditional practice with real benefit in the early weeks — it mimics the snug environment of the womb and can reduce startle responses that wake newborns. The AAP considers swaddling compatible with safe sleep when done correctly: arms snug, hips loose (no tight lower-body wrapping that restricts hip movement), and always on the back.
Critical rule: stop swaddling as soon as your baby shows any signs of rolling — usually around 8 to 12 weeks. A swaddled baby who rolls to their stomach cannot reposition themselves and faces significant airway risk. See our full swaddle transition guide for the step-by-step process.
After swaddling, transition to a sleep sack. Sleep sacks are wearable blankets with a zipper — no loose fabric, no suffocation risk, warm and comfortable. They are the AAP-compliant alternative to blankets for the rest of the first year.

Products That Help You Follow Safe Sleep Guidelines
Safe sleep is largely about what you remove from the sleep environment, not what you add. But a few products directly support compliance:
- Bassinet with firm mattress: For room sharing in the first 4 to 6 months
- Firm crib mattress: The most important single product purchase — see our nursery mattress guide
- Sleep sacks in appropriate TOG ratings: For warmth without loose blankets
- Baby monitor: Allows you to move the crib to the nursery while maintaining awareness
- White noise machine: Supports sleep continuity without any physical presence in the sleep space
