Safe sleep for babies: 2026 guide with AAP recommendations and crib checklist

The first night you lay your baby down alone in their crib can feel like the longest of your life. Monitor in hand, room in darkness, and that question that won't leave you: is she okay? is she safe? At Petitblue, we believe peace of mind isn't something you improvise. It's something you build — step by step, with clear, evidence-based information. This guide brings together the current recommendations from the American Academy of Pediatrics (AAP, 2022 update) so that every night is, truly, a safe one.

What is safe sleep and why does it matter so much?

Safe sleep isn't a trend or a marketing concept. It's the set of practices that reduces the risk of Sudden Infant Death Syndrome (SIDS) and other sleep-related infant deaths (SUID). Across Europe and North America, rates have fallen significantly thanks to prevention campaigns — but SIDS remains one of the leading causes of post-neonatal death in infants under one year of age. The reassuring truth: most risk factors are preventable.

The AAP summarises the ideal sleep environment in three words: alone, back, crib. Everything else builds on these three pillars.

Key principles of safe sleep according to the AAP 2022

Position: always on the back

Your baby should sleep on their back for every nap and every night, until at least 12 months of age. Even if it feels counterintuitive, this position is the safest — even for babies with reflux. Infants' natural protective reflexes prevent choking while lying on their back.

Once your baby can roll over independently (usually between 4 and 6 months), they may stay in whatever position they roll to during sleep. But you will always place them on their back to start.

Surface: firm, flat, and non-inclined

The sleep surface must be:

• Firm: the mattress should not sink when you press your palm against it.

• Flat: no wedges, pillows under the mattress, or positioning devices.

• Certified: look for products that meet current European safety standards (EN 716 for cots, EN 1400 for Moses baskets).

  
  

Inclined surfaces of more than 10 degrees present a real risk of airway obstruction. Bouncers, rockers, and car seats are not safe sleep environments, even if your baby falls asleep in them during a journey.

Space: nothing in the crib

The cot, Moses basket, or bassinet must be completely clear. This means:

• No pillows or cushions

• No loose blankets or duvets

• No soft toys or stuffed animals

• No padded bumpers

• No positioners or nesting pods

  
  

Soft bedding is one of the leading risk factors associated with SIDS. The safe and AAP-recommended alternative is a certified wearable blanket (sleep sack), which keeps your baby warm without any risk of their head being covered.

Sleep space checklist: before you put your baby down

Practices to avoid: what the evidence shows

❌ Soft surfaces and sofas

Sleeping on a sofa, armchair, or soft surface is one of the highest-risk scenarios. If you fall asleep breastfeeding on the sofa, the risk of accidental suffocation is significantly higher than in a cot. If you need to feed at night, do so in bed or in a chair, and return your baby to their safe sleep space before you fall asleep.

❌ Inclined surfaces and positioning products

Sleep positioners, nesting pods, wedges, and any product claiming to keep baby in position during sleep have been withdrawn from the market in several countries due to positional asphyxia deaths. The AAP does not recommend their use, and organisations such as the CPSC (USA) have issued explicit warnings about these products.

❌ Bed-sharing

The AAP recommends room-sharing but not bed-sharing for at least the first 6 months (ideally the first year). Room-sharing reduces the risk of SIDS by up to 50%. Bed-sharing increases risk especially if baby was born premature or at low birth weight, parents have consumed alcohol or sedatives, there are soft blankets or pillows in the bed, or either parent smokes. Certified bedside cribs attached to the parents' bed are a safe alternative that allows closeness and night feeding without the risks of direct bed-sharing.

Frequently asked questions

My baby has reflux. Is it still safe to sleep on their back?

Yes. The AAP and paediatricians are categorical on this: even with reflux, back sleeping is the safest position. Infant reflexes protect the airway, and the risk of positional asphyxia on an inclined wedge is greater than the risk of aspiration when lying flat on the back. If reflux is severe, speak to your paediatrician before making any changes to sleep position.

Should premature babies also sleep on their backs?

Yes, especially them. The NICHD and AAP recommend adopting the back-sleeping position as soon as the premature baby is stable and preparing for hospital discharge. In the NICU, other positions may be used for medical reasons, but at home the rule is the same: on their back.

When can I add a pillow to the cot?

Pillows are not recommended before 2 years of age. After that age, if the family wishes, a small firm pillow may be introduced, though most paediatricians do not consider it necessary.

Does a dummy protect against SIDS?

Yes. Evidence links dummy use during sleep with a reduced risk of SIDS. The AAP includes dummies as a protective strategy. There is no need to reinsert it if it falls out during sleep. If breastfeeding, it is best to wait until feeding is well established (usually 3–4 weeks) before introducing one.

A safe environment is the greatest gift you can give

At Petitblue, we design every product with this balance in mind: safety that doesn't sacrifice comfort, connection, or the beauty of the bedtime ritual. A sleep sack that warms without risk. A lamp that creates atmosphere without over-stimulating. A ritual that turns bedtime into a moment of connection, not anxiety. Because a peaceful night is the beginning of a brighter tomorrow.
