Hi I've never looked for help but now we are desperate my autistic son who is top off spectrum age 16 and 19 stone is ruling the house and going into full meltdown if he hears the word no.he shares a bedroom with his oldest brother it's always worked out well.but two weeks ago he decided he no longer wants his brother in the bedroom and whenever his brother enters the room he drags him out if his brother resists he goes into instant meltdown and starts punching his own head at full force until his brother leaves then he slowly calms down. The issue is we only have a 3 bedroom house and I have 4 kids so there's no choice but to double up with my boys.do I face off with my autistic son and hope he will just stop or will my other son spend the rest off his life on the sofa.we get no support from anyone yet this new trait my son has got into is a nightmare. Any advice would be appreciated thanks.
