I would LOVE to have DS7 move up to the next class, however, ... My son is very very stubborn so to add him in a situation with whom he's already having problems with would most likely end up in a worse situation.
I have to agree with you there, but if DT is so sold on your DS, perhaps you can remind her what she had to go through to really see your son, and how long he had to wait, and maybe, just maybe, in addition to the lovely note, she can influence the school to promote your son on the last day of school to the next grade up so that he can start the next year as an official X+1th grader.
Anyway - it's great when a classroom teacher really starts to work with an unusual child. Enjoy the next few months!
