Practicing for the Thanksgiving performance

This week has proven more difficult for Thomas.  The class is practicing for a Thanksgiving show for the parents next week, which is throwing him off a bit.  He has mentioned a few times this week that he doesn't want to go to school, which is new. He didn’t want to participate in gym this week either.  The preschool is having a small Thanksgiving show in the classroom for the parents on Wednesday, but Thomas has not been willing to stand during the songs.  They are not expecting him to do them, but he can’t seem to stand.  We tried making him a helper and giving him a prop to hold, but neither have worked  We gave him a week to give this a shot and then after talking with him, I asked what he would like to do.   He decided that he wanted me to pick him up early that day.  He will only miss the last fifteen minutes of school.  I have mixed feelings about him avoiding these types of things, but right now these four turkey songs are not worth ruining all the progress he has made this year.   We will be picking him up early that day.
