My 3 year old non verbal autistic son has tantrums sometimes where he starts screaming and hitting and I have ways of helping calm him down like his sensory brush. Which a lot of the time does help. But he has a one year old sister and as a mom I’m also protecting her from him shoving her or hitting her. What are some therapies or ideas that you guys have or learned about for correcting/bettering these behaviors when they are present?? Thanks!
