When should babies stop wearing sleep sacks?

Unlike a loose blanket, a sleep sack/sleep bag is like a “crib blanket” and will keep your child’s temperature regulated while keeping their sleep space safe. The AAP’s recommendation is that nothing is in the crib with your baby, just a tight fitted sheet until they’re 12+ months.

Are sleep sacks safe for 1 year olds?

Yes. It is generally safe for infants to sleep in a sleep sack which allows their arms to be free and hips and legs to move once they start to roll over. This ensures that they are able to move about freely and can push themselves up when they start to roll over on their own.

Can babies sleep without a sleep sack?

Sleep sacks help babies maintain the correct body temperature without becoming overheated from too many blankets. Babies are at higher risk of sleep-related death if they become overheated. If you do not have a sleep sack, your baby will be warm enough in just footie pajamas.
