To sleep or not to sleep? That is the question.

During Christmas Cordelia stopped taking naps. Between being out of our routine and the boys being home, she just wouldn't lay down. We figured she would return to naps after the break, but we were sadly mistaken. Now she takes a nap maybe twice a week. Right now I don't know what to do with her because her sleep is so out of whack and we lose whether she takes a nap or not. When she doesn't take a nap she becomes down right unbearable at about supper time. However, if she does take a nap, she's up until 10:30 at least. I hope this is a short passing phase. I know like all things this all shall pass, but I'm ready now.
