Looking back on my life, now knowing that I have autism spectrum disorder, I would say yes, even though I and 3 cousins are diagnosed ASD, and my dad and grandfather were probably on the spectrum. It's not a bar to having a good life, especially with support. When I was in my twenties, I thought I was too messed up to have kids, partly because I had a pretty messed up childhood and didn't think I knew how to be a good mother. Then I had a pregnancy scare after a one-night stand. I spent a scary month trying to decide what to do -- abortion? adoption? keep it? call the (one night stand) father? At the end of the month, I decided to keep the baby, and I started to think of this as a blessing in disguise. Unfortunately, I became very ill soon after, and lost the baby.
I thought about trying to get pregnant intentionally, but was afraid I was too crazy. If I had known what my problem was, and had been able to get some guidance and support, I think I would have tried to have a child.
I've heard of some people with ASD having children on the spectrum, and still having a happy, well-adjusted family. I'm sure it's a big challenge, though, so I can certainly understand you wanting to go with adoption.
