My sons like their weighted blankets at bedtime! I've even borrowed them from time to time.

I honestly can't remember what I did when my older son was at his peak with meltdowns (I prefer the term meltdown rather than tantrum; meltdown seems more reacting to/overwhelmed by environment, tantrum seems more willful). I think I was just living moment to moment trying to get through the day.

He didn't get diagnosed until 1st grade. He got some OT in school then we did more (private OT) over the summer between 1st and 2nd. He was most agitated at bedtime so I tried joint compressions at bedtime, along with a CD of ocean waves for white noise, and those seemed to calm him.

Also since he has low muscle tone, the OT suggested doing wheelbarrows down the hall to his bedroom before bed. The muscle work would be calming, she said.

Good luck!
