@ MosMom: Maybe have it put into his IEP that he needs to be able to go to a quiet space when he’s having a meltdown, instead of being sent home? Both the school and my parents tried to punish away my symptoms of ADHD, so elementary school wasn’t too bad, the worse that would happen was I would start crying. Which would then lead to my classmates picking on me. Which is part of why I now go to my room if I feel a meltdown coming on. I’ve had years of people telling me that my ADHD is inappropriate behavior, and if I can’t control the behavior, I try to hide it, in either suppression or I hide until the behavior passes. I have found lavender essential oil is very helpful for calming. Maybe try giving him some that he can smell when he feels a meltdown coming on.
