Frequently Asked Questions
When should I move my baby from a swaddle to a sleep sack?
Start the transition once your baby shows signs of rolling (usually around 4–6 months) or repeatedly breaks the swaddle. Rolling increases SIDS risk when a baby is swaddled, so move to a wearable blanket before or immediately after rolling begins. A gradual introduction at naps before nights often eases the change.
How can I transition with minimal sleep disruption?
Use a phased approach: loosen one arm out of the swaddle for several nights, then both arms, and introduce the sleep sack at daytime naps first. Pick a breathable, soft sleep sack (TOG 0.5 is a good baseline), keep bedtime routines consistent, and use the sack’s bottom zipper for quick diaper checks so you don’t fully wake the baby.
Are sleep sacks safe, and what features keep them safer than blankets?
Yes—wearable blankets are safer than loose blankets because they can’t cover the baby’s face. Choose a sleeveless, appropriately sized sack that fits snugly at the neck and shoulders, has no loose ties, and follows AAP guidance. Features like a secure neckline, zipper cover, and breathable fabric further reduce risk and overheating.
