New here and looking for some advice please

First of all hi all and thank you for taking the time to read my post

I am a career for my 4 yr old son who has been diagnosed with asc and my partner also recently diagnosed with aspergers syndrome 

Well I'll get straight to the point my son was diagnosed in jan this year after 15 months on the pathway he also may have ADHD but can not be assessed for this until school age he is currently waiting to hear about a statuary assessment process to attend a specialist school in the local area I have come to terms that my son is unique and special in his own way but I am really struggling with his behaviour we have been referred to occupational therapist and a sleep counciler for his sensorya issues and his sleep problems but I don't know where toreturn to for help in disaplining him and what methods for when he's inappropriate we do have timeout which we use but he thinks everything is a game which just results in us all getting frustratedwhich results in him physically hurting myself or his brother the dog or himself I have bruises all over due to this as I'd rather he took it out on myself than the others but it's becoming harder with him getting older and stronger we have just started using pec cards but they are still new to myself so struggling a bit to get used to them but I was wondering if anyone else has any strategies that worked for their child to learn they are doing wrong? As I don't know who else to asAmanda just feel in a never ending cycle at the moment and on the brink of a nervous break down especially as he is constantly on the move so hard to attain attention from him and no sense of danger at all I found his bedroom window wide open a couple ofa nights ago and he just doesn't see the dangers and when out hits people for sitting next to him and is very rude i know he doesn't understand but how can I make him see this isn't acceptable behaviour? 

Thank you for any advice possible
