Lots of empathy JDAx3, but few suggestions. With Miss 8, we were continuously exposing her to new things, new sports, new activities and not a school term would go by without us trying out something new. It wasn't until we went to New Zealand for a few weeks, got the kids out of their comfort zone and carefully observed them that their passions came to life. We watched Miss 8 draw constantly while she was away; it was more than just something to do, but something far more cathartic. Perhaps your son's passions really do exist - just under wraps?
We've struggled all year to increase Miss 8's care-factor with school work. The grade skip certainly helped a little, but I'm hoping that care will come with age too. Finding the right art teacher, music teacher, school teacher is critical, but it doesn't solve everything - just another part of the puzzle. Good luck solving yours... jojo
