How do I swaddle a newborn safely?
If you swaddle, place your baby on their back and stop as soon as they show signs of trying to roll.
The short answer
If you swaddle your baby, the AAP says to place them on their back for every sleep and stop swaddling when they show signs of trying to roll. Weighted swaddles aren’t safe for infants.
Swaddling is optional
Some caregivers use a swaddle to help comfort a newborn. It isn’t required, and it doesn’t prevent all waking or crying. If you choose to swaddle, use current American Academy of Pediatrics guidance and ask a doctor to demonstrate a safe method if you’re unsure.
Place a swaddled baby on their back for every sleep. Use a light material, keep the face uncovered and leave enough room for the hips and legs to move. Loose fabric can cover a baby's face, so check that the swaddle stays secure.
Know when to stop
Stop swaddling as soon as your baby shows signs of trying to roll. Don’t use a weighted swaddle or weighted blanket. Watch for signs of overheating and keep the sleep space firm, flat and clear of loose bedding.
A product that compresses the arms or body is still a swaddle even if it is sold as a sleep sack. Check the product instructions and ask your baby's care team if the fit or stage is unclear.
Choose a safe sleep space each time
Swaddling doesn’t change the basic safe sleep guidance. Put your baby on their back in a separate, firm and flat sleep space with no pillows, toys or loose covers. Don’t swaddle in a way that restricts hip movement.
