My 3 month old is a 40min sleeper and can only handle 40mins awake time before she gets grizzling. She is super sensitive to everything so going out with her is impossible. People say babies get better around 3 to 4 months...is this true for all of them or will these problems, and the short awake time continue until she sleeps longer than 40mins? I've tried everything to extend naps and we are having some 1.5 hour ones now but alas the awake time is still not increasing. Feeling overwelmed. When will it get better?
