Most parents transition their newborns from the bassinet to the crib at around 3 - 6 months. If your little one is sleeping peacefully, there’s no need to rush the process, but you also don’t want to wait too long. The more comfortable your baby becomes in their bassinet, the more likely they are to resist the transition into a crib. You’ll also want to avoid transitioning during a time when there are other changes to your baby’s routine, like during a vacation or time change.
