DD is 16 weeks old and although she is FAR from STTN, I don't change her diaper after midnight because it always wakes her up. During the day I would change her diaper right away even if it's just a tiny teeny blue line (we used Pampers Swaddlers), but at night time I don't want to risk waking her. Even though it doesn't seem to bother her I still feel guilty knowing she is in a wet diaper (definitely not poop!). In the mornings, her diaper is always full but no leaks. So mommas, do you change your LO's diaper during night time feedings? And also, at what age did you start using overnight diapers?
