Just something I notice on every thread on mumsnet, people mention their "child with ASD". It seems so utterly common on here that it makes me wonder if there are any families out there who still have no children with ASD at all. I have one with (not yet diagnosed but quite evident) ASD and one neurotypical. Growing up I didn't know any children with ASD until a boy joined our secondary school and we were all made aware of this by our teachers in a bid to accept him despite his "odd behaviour". That was one child in a school of 1200 pupils. Now there are one or two in every class. It's quite shocking.
