1 The average age to stop swaddling baby is around 3 or 4 months of age.  Newborns are born with a startle reflex, called the Moro reflex, and most babies donât outgrow it until 4 or 5 months of age.
You should only use swaddling and sound when your baby is sleeping or crying. When theyâre awake, babies need time to practice using their muscles. After two to three months most parents only wrap their babies for sleep. I recommend continuing the sleep swaddling for at least four months. Thatâs because unswaddled babies can pretty easily roll from the back onto the stomach (a riskier position).
