Yeah, I used to deal with that when DS was an infant/toddler. I would try to convince people of the seriousness of his issues, and all I got were those condescending looks that people reserve for the mentally ill. I lost family relationships and friends over this. It was a waste of my precious energy. If you need support, talk to other SN parents and learn to ignore the well-meaning comments from total idiots (I just smile and walk away). I think that our reality is so different, it's hard if not impossible for others to conceive of what we do for our kids every day.
