Agreed. My friend has a son that is autistic & I have a child at the daycare I work at that is very high up on the autism spectrum. People who say autism isn't real irritate the shit out of me. I take it you have autistic child?
I actually don't think this is an accurate statement, I think that there are a huge number of people who could offer great parenting tips for their autistic child, even if they themselves don't have one.
I could 100% offer a mother of an Autistic some really useful tips to help her son (and in turn her). I don't have a child with Autism but I do know her child, and could really help her out.
