I know I can't do anything about it, but I feel quite sad about it, as I just don't think their relationship will be a happy one.
Ds will be going into yr1, and imo this teacher is more suited to teaching older children.
Dd1 had her in yr 1 aswell, and although she is a good teacher, she just doesn't seem to get small children. She doesn't know the meaning of the word fun, and I am not sure I have ever seen her smile.
Ds can be a complicated little chap, and I think they are going to clash.
