Once I found out DH was Aspie, I wondered if it was something that could be passed down to our children. I didn't know about the genetic factor at the time. With my daughter, I didn't actively try to prevent any type of autism.
With our second baby, however, I was more aware. Everything freaks me out now. I look at him every day and wonder "will he have Asperger, too? Will he be autistic? Profoundly so?" I read and read on ideas about what causes it and how it might be prevented. It drives me crazy that no one really knows exactly what causes it and I find new research all the time. First it was vaccines and then they proved it wasn't and I believe that. Now they are saying it might be vaccines again, but not exactly just that - a combination of autism genes and an overload of heavy metals in the system which can be brought about by vaccinating. Now I ask our doctor about vaccine ingredients. Neither child has been vaccinated yet. I wait until they are 4 and then I only have a vaccine done if there is an outbreak. Our pediatrician knows this and keeps me updated. We are having a pertussis outbreak right now, so DD is going to have her first-ever shot in a few days.
Everything worries me now. Do you do things to try to prevent it? Even things you aren't sure about, just to be safe rather than sorry? I have read that it is more prevalent in boys (DD and my stepdaughter are not on the spectrum) and I keep meeting more and more moms with Aspie partners who have children with autism, many of them profoundly autistic.
