You seriously don't think "we should decrease the number of people born with Down Syndrome" is a morally defensible position either?
I don't think "we should decrease the number of people born homosexual" is a morally defensible position, but decreasing incidence of Down Syndrome, or autism, or Fetal Alcohol Syndrome, are absolutely morally defensible positions, and in fact, are regularly done -- people everywhere socially discourage pregnant mothers from drinking alcohol, for example, and I don't think the discouraging third-parties are the ones who are in the wrong in that situation.
I think having a child AT ALL, regardless of any other concerns, is an individual decision that should be made by mature, capable adults. I don't think it's necessarily a "morally defensible position" to have a third kid when you're struggling to take care of the previous two just because you belong to a religion that thinks prophylactics are immoral, and I would never, for example, judge a potential parent who decided to terminate a pregnancy because they were told it is unlikely their child will be born alive, and even if it is, would be unlikely to live for long.
