Silly question, but how long do babies wear gowns to sleep in? I have some in newborn and some 0-3 month. But after 3 months can they just start wearing footies to bed and be fine? Or should I buy a few just in case? Thanks in advance!

Edit: just to make sure I’m not confusing I mean like nightgowns not the sleep sacks 😊
