I think you're at the perfect point to schedule a meeting or at least email and say you know she's getting to know the kids and preparing appropriate differentiation for them all, and you'd like to know possibilities for your child and offering help/insights about him that could be useful for her preparations for an appropriate year for your son SWEET HELPFUL INNOCENT SMILE. Just enough to give her a chance to do something, and see what it is. Then if that something is nothing or not much, you know you've got to go in for a serious advocacy meeting. Between maternity leave and being overly trusting of our school's big gifted standards/differentiation focus we wait WAY too long. You do have to give them what seems like a long time at the start of the year as they teach routines and get to know the kids and then implement different groups etc, but a nudge to be sure she's thinking of your child can't hurt.
