Hello!I am sorry that your son and you are going through this. I really am.As a child I had sensory overload and temper outbursts.It sounds like your son has trouble with transitions and needs to have a weighted vest to sooth himself. I was thinking the vest can help with sensory overload. Also a time out to ease himself into tension fraught circumstances.It is possible his diet also makes him prone to temper outbursts.Allergies can do that.I have a book called Secrets to controlling your weight cravings and mood Second edition by Maria Emmerich. The book has a neurotransmitter deficiency checklist and tells you what foods and supplements that remedy them. I also read about a gluten free cookbook about a single dad and his autistic son. Well his son was having temper outbursts and his autism was being treated by medications and OT. So his dad tested his son for allergies. Sure enough gluten and dairy were the culprits behind his behavior. I do not have the name of the cookbook or author. But that did prove to me that diet can have a big impact on behavior. Good luck to you both and I will pray to the Goddess that you both get a solution and relief from your suffering.
