My 4 year old DS has autism (classic, non-verbal), now my 19 month old DS is showing signs of autism, he is very different to how my 4yr old was at that age but still showing signs. I am 31+5 weeks with DS3 and I can't stop thinking he might have autism too. I just have a bad gut feeling that all three will have autism and its making me feel really down! 
Has anyone else got all their children on the spectrum? How do you cope? My DH thinks I am over reacting and thinks DS2 is fine but he also thought the same about DS1 at the beginning when I first had concerns (when he was turning 2 and still not talking). And it doesn't help that my Mum asks every week on the phone (we live in different countries!) how DS2 is doing with development, speech etc, I just want her to stop asking, my health visitor will not do anything until he turns two so what is the point of keep asking me and getting me more and more stressed/worried etc, i really don't need this at 7 months pregnant!
I don't really know what I expect from this post, I hope I don't sound stupid for posting!
