Did it strike your house? When? In what form?
R is 16.5 months and suddenly went from sleeping until 6:30 every morning, to waking at 5:30. 6 is sleeping in. We thought that transitioning to one nap was the issue, but now he's on one nap and still rising early. I'm wondering if this is some form of regression? The other possibility is he has a skylight in his room and it gets light here SO early now, probably by 5:30 it starts getting light. He has all his molars. I don't see any canines working through....
HELP!
