7 year old son with potiential Autism spetrum disorder

Hi

I am a parent to a lovely boy who is reaching the end of begining diagnoised with a Autisitic spetrum disorder.

He goes to mainstream school which is supporting him well but he doesn't play with the other children much.

Its been a bit of a rollercoaster year and everything seems hard at times. Would love to meet up with other parents with children and get some support/have a chat. Sometimes it would be  just nice to be with people who understand and don't judge.

He is in swimming lessons but i am having issues with the teachers and Georges behaviour at times.

Is there any help support for children once diagnoised to help them?

Thanks x
