Safe sleep, birth to 12 months
Am I swaddling safely, and when do I stop?
A good swaddle has three rules and one clear end date. Here they are, in the reviewed wording, so you can wrap tonight without second-guessing.
The short answer
Back, snug at the arms, face clear, and stop at the first sign of rolling.
Swaddling can help some newborns settle, and it works with back-sleeping in the early weeks. If you swaddle, always lay your baby down on their back, keep the wrap snug at the arms but never over the face or head, and make sure it can't come loose. The end date is behavior, not a birthday: stop as soon as your baby shows any sign of trying to roll, which can begin as early as around 2 months. And because a wrapped baby is a warmer baby, keep an eye out for signs of overheating.
What's going on
Three rules, one end date, in the reviewed wording.
First, why swaddling helps at all, and why it has an expiration:
Snug swaddling can help soothe some newborns and support back-sleeping in the early weeks.HealthyChildren.org (AAP), Swaddling: Is it Safe for Your Baby? · 0-3 months
Reviewed wording: "Snug swaddling can help soothe some newborns and support back-sleeping in the early weeks. Stop swaddling as soon as your baby shows any sign of trying to roll, which can begin as early as around 2 months, because a swaddled baby who rolls onto their tummy can't easily lift or turn their head."
Second, what swaddling does and does not do. It is a comfort tool, not a protection tool, and position still does the safety work:
Swaddling itself hasn't been shown to reduce the risk of SIDS, though it can help some babies feel calmer and settle.NICHD Safe to Sleep, FAQs · 0-3 months
Reviewed wording: "Swaddling itself hasn't been shown to reduce the risk of SIDS, though it can help some babies feel calmer and settle. If you swaddle, always lay your baby down on their back, keep the wrap snug at the arms but never over the face or head, and make sure it can't come loose."
Third, warmth. A swaddle is an extra layer wrapped all the way around, so it is worth knowing what too warm looks like:
Swaddling can increase the chance of overheating; signs include sweating, damp hair, flushed cheeks, heat rash, and rapid breathing.AAP HealthyChildren · 0-4 months
Reviewed wording: "Swaddling can increase the chance of overheating; signs include sweating, damp hair, flushed cheeks, heat rash, and rapid breathing."
If your baby hates the swaddle, that is allowed too. Swaddling is optional comfort, not a requirement, and a baby who sleeps unswaddled on their back in a bare crib is doing safe sleep exactly right.
When to call
If the wrap is right but something feels off.
This page is education, not diagnosis. If something feels wrong, call your pediatrician (or your OB for your own body). In an emergency in the US, call 911.
Tonight's small action
Do a two-minute swaddle check at the next sleep.
At the next wrap, run down the list from this page: baby on the back, wrap snug at the arms, nothing near the face or head, and give the swaddle a gentle tug to confirm it can't come loose. Then look for the overheating signs the guidance names: sweating, damp hair, flushed cheeks. If you see them, your baby is too warm. Last question before you step away: has your baby shown any sign of trying to roll? If yes, tonight is the night the swaddle retires.
