My son is two years old and it started yesterday and he did it again today. He has never taken long naps like this before I just don't understand. Well yesterday we both went down for a nap and it was 1:30 when we did and we woke up at 6:17 it was crazy. I let him stay up till he passed out which was 10:30pm and he woke up at his usual time which was 6:30am. has anyone elses children done this?
