Human genetics is a crap shoot. You never know what you're going to get. My mother had two children with neural tube defects - my sister, who died at birth, and me. I have always been worried about passing along such defects (anencephaly, spina bifida) to my children. My son's spine is perfect. But his eyes, that's another story. I had no history of his eye problems in my family, nor are they in Josh's. But it happened with Aidan. Am I a bad person because I want to have one or two more children even though the chance of them having my problem (spina bifida) or Aidan's problems (coloboma, etc) are raised? I don't think so. So long as you realize that problems or not, that child is your flesh and blood. Would you love them any less if s/he had Downs Syndrome or Autism or spina bifida? If the answer is yes or maybe, then yes - you ought to think twice before you have any kids. Otherwise, do what your heart says and realize that just because it's in your family doesn't mean a thing.

That makes me sick.
