My soon to be 5 year old is causing endless worry, his behaviour in his mainstream school is getting worse and his teachers constantly complain. He is nonverbal for the most part and simply refuses to follow instructions and is just in his own world. I feel a bit let down by local authorities as they have never provided anything useful in the form of therapies for him or to us as parents, despite us raising concerns since he was 2. I feel we have lost 3 years (not helped by the pandemic) and I feel guilty as we never sought any private treatment or advice. We are getting nowhere with the official NHS channels so I'd like to try private alternatives if anyone has any recommendations in London or beyond? We desperately need to find ways to improve his behaviour and start co-operating otherwise I just don't know how we'd cope if and when his school inevitably expel him. Thanks.
