Hi, I am 35 and pregnant with my 4th child. My youngest has Autism. I know that already having a child with Autism my baby might also have Autism. I also know that being 35 there is a higher chance that my baby could have Down Syndrome. My question is how having a child with Autism effects the chance of my baby having Down Syndrome? Could it increase the chance more than it already is with me being 35, or does the chance remain the same as any 35 year old?
