Autism parents how long has your child had a meltdown and or tantrum for. I’ll go first. My lovely 9 year old has had a meltdown so far today for an hour and a half. His ABA therapist is just waiting it out. It’s all over denied access to his hoodie. He loves hoodies but it’s hot outside and in the house. We are trying to get him to understand temperatures and he doesn’t want to. It’s really a comfort thing.
