Not off to a good start

2nd day of prek and I'm already getting a call from the teacher. The regular teacher wasn't there Monday but she was today and while I wasn't told Monday but my son doesn't want to take a nap at school. She called me at 1:30 I was already about out the door to head there since they get out at 2:00. By the time I got there and walked to the class poor kid had cried himself to sleep. Teacher informed me that she can't deal with him if he is gonna cry. I tell her that he isn't used to going to sleep anywhere but his house because we never go anywhere and he is with me or his dad he has never been to a sitter. Not her problem this I know but I tried to pled his case.
