Frequently Asked Questions
When should I stop swaddling and switch to a sleep sack?
Most babies show signs between 2–6 months: they roll over, push up on hands, or break out of the swaddle. Once rolling begins, the American Academy of Pediatrics recommends stopping swaddling and using a wearable blanket or sleep sack that keeps the baby covered without restricting movement.
How do I make the transition gradual so my baby still sleeps well?
Try a stepwise plan: start with a swaddle that allows one arm out for several nights, then both arms out in a swaddle-like blanket or a transition swaddle, and finally move to a sleep sack. Use the same pre-bed cues (feeding, dim lights, white noise) so the new sleep outfit becomes part of the routine rather than the trigger for wakefulness.
What features reduce night waking during the transition?
Key features are breathable material to prevent overheating, a snug-but-not-tight neck/shoulder fit to mimic swaddle security, and a bottom zipper for fast diaper changes. A hip-healthy roomy sack prevents discomfort in legs, and durable zippers reduce interruptions from malfunctioning closures.
