I have a 3 year old son with PDD-NOS. If I choose to have another child is it likely he will be on the autism spectrum as well?

  • I also have a child with autism. From what I've researched and learned is that there's about a 5-8% chance that the siblings will have autism. Has has had any bloodwork done to check for the fragile x chromosome? My son just had it done and if that's present the chances are supposed to be higher.

  • The chance of having one kid with autism is 1 in 150. The chances of having a second with autism are slightly higher.

    I have two suspected of being on the spectrum. (they're so close together, there was no way to know...)

  • Hello, I have two diagnosed with autism. My first son, is my only "typical" child who does not have the diagnosis. My second and last born both have a diagnosis of autism. It's pretty crazy statistics for me anyways. I have only 3 boys, and got two on the spectrum, back to back in birth order.
