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.
At around six weeks old, you should release at least one arm, so that the baby can put the hand in his or her mouth for self-soothing. For naps and night sleep, you can swaddle your baby (except for at least one arm when older than six weeks) for as long as the baby likes it. Some babies wonât settle without a nice swaddle even when approaching their first birthday! But long before that, both arms should definitely be released!
