Steven Levitt writes on the recent study suggesting a majority of parents decide to abort when faced with a diagnosis of Down Syndrome:

I suspect, though, that many parents of children with Down Syndrome would say that raising that child is incredibly rewarding. As a parent, I have found that the greatest pleasures are in watching your child achieve a goal. It doesn’t matter what; it can be anything. Being up on stage in a first-grade play, buying a trinket at the store by herself for the first time, riding a bike. It is always especially touching when a child overcomes obstacles. A shy child goes off on her first sleepover, for instance. My guess is that the underdog nature of a child with Down Syndrome makes the little accomplishments that much more satisfying for their parents.
