I have a daughter with an August Birthday and your son is a full 17 months older than my daughter and they are in the same class.
I can't stand it that you say that the classwork is too easy and your son is not academically challenged.
Perhaps you wouldn't feel that way if you sent your son to school on time. I bet my daughter would look really talented too if she were compared to kids much younger- rather than just a hardworking kid.
Eh. My son is the youngest kid in his class and the second youngest in his grade. Academically, he take any redshirted kids in his grade. Socially it can be tough, but he has some friends (a few nice girls and quieter boys).
