Swaddle vs sleep sack
Swaddles and sleep sacks are clothing, not SIDS prevention. AAP: swaddling does not reduce SIDS. Stop when rolling starts. No weighted products.
We are not pediatricians. This is not medical advice. Your pediatrician knows this baby.
A swaddle or a sleep sack is clothing. It is not a safe-sleep product. The AAP 2022 floor stays the same: back, firm, flat, empty, room-share. Swaddling has not been shown to reduce SIDS. We will not sell you one as if it had.
What a swaddle is for
Some newborns startle (Moro) hard enough to wake themselves. A hip-healthy swaddle — arms in, hips free to flex — can quiet that for a while. It is optional. Plenty of babies skip it.
Rules if you use one:
- Always on the back.
- Snug at the chest, loose at the hips. Tight-hip “sausage” wraps are a hip problem, not a sleep hack.
- Stop when rolling starts, even if that is earlier than an auntie promised. A rolled, wrapped baby cannot get a face free.
- No weighted swaddles. AAP advises against weighted sleep products. See what to skip.
What a sleep sack is for
A wearable blanket (sleep sack) is a zipper layer instead of a loose quilt. It is still not bedding in the crib. Fitted sheet only on the mattress. Bare is Best.
Switch to a sack — or just a sleeper — when swaddling ends. You do not need every size on the registry before birth.
What we will not do
- Rank brands
- Claim a sack “prevents SIDS”
- Tell you to keep swaddling after the first roll “just at night”
- Recommend weighted sacks, “transition” wings that still pin arms after rolling, or velcro systems as medical devices
