How do I transition from swaddle to sleep sack?

Gradual transition steps

Move from a swaddle to a sleep sack when the baby starts showing rolling behavior or seems ready for more arm mobility. A phased approach helps maintain comfort and safety.

Transition plan:

• Start by swaddling with one arm out for a few nights to allow the baby to get used to more movement.
• Move to a sleep sack that keeps the lower body snug but allows arm movement.
• Practice naps in the sleep sack before using it overnight to build familiarity.

Safety and timing

Choose a sleep sack appropriate for the baby’s size and season to avoid overheating. Once the baby can roll consistently, discontinue full swaddling and use a sleep sack with room for movement. If you have concerns about timing or your baby’s sleep behavior, discuss options with your pediatrician.
