Parents of children with Down syndrome are beginning to wonder whether the services and accommodations they've fought hard for could fade away if kids like theirs are slowly weeded out of the population. "You want a perfect baby, and the easiest thing to do is to eliminate a child that won't fit into that mold," says Theresa Howard, a N.J. ad copywriter who found out after her daughter, Lydia, was born in 2006 that she had Down syndrome.

We've had some discussion on this site in the comment section about promoting favorable parenting to children who have a different sexual orientation than expected. But when we review this problem we see there are many ways that children can turn out different than expected, some with the prospect of early death.

The question isn't whether or not you are lucky enough to have the children you have. The question is are the children you have lucky to have you as a parent? Yes, if you care about them and are the best parent you can be they are very lucky to have you as a parent. So much about your children may not be fixable, but they can be helped greatly by your love and support. And then the things that are fixable will respond to that support and work out for the better.

Marriage, rooted in the commitment to an uncertain future, is readily understandable to people who understand it as a mooring for responsible procreation. Procreation, more than any relationship you can choose is, uncertain. And the child who is a product of your relationship deserves your best support and guidance. And marriage, rooted in that understanding, will benefit everyone and even go along way to solve homelessness for all children.
