HI Lynn - welcome aboard and thanks for sharing. What State or country are you located in? IS the OCD an official diagnosis? I have not been able to get one for my son and not sure which avenue to take to get that, which type of Dr did you see and do you do any of the CBT therapy?
My son really does not have meltdowns at school, he saves them for the way home when things get uncomfortable or upsetting on the playground, which happens at the end of the day anyway and he holds it in until we get home. I think most kids on the spectrum release their tension in the comfort and privacy of their homes once they get out of school. Not great for the parents, but at least they can maintain until that time.
