We visit my father in law with his wife and two kids. One is 7 and has level 3 autism (needing the most support) he is mostly non verbal and he is quite a big strong boy, very solid and big build. I am looking for a little advice on how i can protect and help my 2.5year old and 4 year old. Sometimes the boy will be busy doing his own thing and then will walk up to my 2.5year old and push her over. Or randomly come to my son and hit him even through he was just displaying being content. He is extremely unpredictable and it is so hard i am constanly running around to protect both my little ones. My father in law and mother in law do there absolute best with him and he is in therapy and behavioural therapy but its at the point i am feeling like the best option is to not go there or bring my kids untill maybe my kids are bigger or the boy has had some more assistance with his bahviour. If that makes sense. I have worked around some other children with autism but this is very different and i want to do right by all children involved. When we use to come over he would come say hi and we would greet him and say safe hands so he would touch my daughter or son gently and then quickly pinch them super hard. So now we say no touching baby ( because she is scared of him) and if he cant have safe hands he cant touch. We know most of his triggers and they are easier to manage but its the unpredictable actions that may seem not so harmful to someone his age but to my little ones who are light as feathers have actually really hurt them. For any parents of children with autism what is the best way to go about this. I appreciate any help :)
