Mr W (26 mos) spends his first hour with older kids as a trial. He has been ready for months - just has some potty issues to work on. We've been getting some resistance to going to school lately and Mr W has indicated he wants stay in the older classroom.
Other than one kid in his normal class, who is a real hard charger, he prefers being with the older kids. And the older kids just love him once they get past his size issue. I had two 5 year olds come up to me last week and tell me that "Mr W is a lot of fun! We taught him so many things! He learns really fast!"
They have to watch MR W with his age peers as he will try to do things with them that they are not ready for. He likes for one of them to sit in the wagon while he pushes it at high speed. Not good. And they pick up things from him that are dangerous for them - i.e. he can use a sharp knife to cut up food, etc. This is another reason for him to be with older kids. He may get some lumps, but at least he won't be handing them out to kids who are not ready for it. They also have to do something else with Mr W during class lessons as he will blurt out the answers.
I think a trial move is worth it. Your DD will really enjoy it and with her charisma she will become a fixture for the older kids.
