To me, it sounds like a mom's natural bonding with her young son is being threatened. I feel for you.
My experience with local so-called top-notch schools was not that impressive, once I really observed the day-to-day happenings. Looking back, having my child in our home environment was important in so many ways (esp at the young ages). As time moved on, academics took a more serious role; hs'ing offered opportunities that would have been impossible in a traditional school setting.
When I was in similar shoes many years ago, I chose the hs'ing route. I believe we share a priceless closeness because of that decision. Not always easy, but absolutely no regrets.
Follow your heart.:)
