Hi! I have noticed that if I leave Olivia's in overnight, it is more difficult to remove because the hair tangles around the band. So I recommend removing it before bedtime...but her hair isn't real long either so it's not like it's in her eyes or anything when it's not in a topknot.
(In our avatars, I think our babies look a lot alike, don't you?! except Olivia has some darker brown on her nose)
