Mum of autistic Son

Hi everyone,really new to this and have never used a chat forum before!My 2.5 year old son has recently been diagnosed with ASD. If I’m honest I knew about a year ago but he was way too young for the doctors to pay attention. I’ve always struggled with him and blamed myself because he was such hard work and that I was maybe finding it way harder than I should of. Now we have a diagnosis, I realise that anyone would have felt the same caring for him as he does have additional needs:) I’m really looking to chat with mums and dads who have autistic children and would like any tips or advice on making my child as happy and secure and safe as I possibly can. My son has always had sleep issues and suffers from sensory overload and sensory deficit, any advice would be very welcome,thankyou!
