However, if your baby is not in a good routine, I would recommend swaddling him until he is four months old, or when he starts to move more during his up time. This will need to be a slow transition. Because your baby will not feel as safe and secure as a baby in a routine, taking the swaddle away cold turkey could cause problems. If you are going to take the slow approach to weaning your baby off the swaddle, you need to do it well before there is a risk to your baby’s safety. If you wait until your baby is older than four months, he might become tangled in or covered by the swaddle.
