Has anyone's 18 month gone from 1 nap to seeming like they need 2 naps again? My LO goes to bed at 7:30. Wakes once at night for milk like always and wakes anywhere from 7-8AM. She's is SO crabby these last couple of days. I'm also thinking maybe it's from the weekend? Went to bed later on Friday and Saturday and than woke up later too ? Should that effect her that much ? We really try sticking to a strict schedule, but with family around for the holidays it's going to be tougher.
