For starters, I agree completely that we should do everything possible to support single mothers. It is harder raising a child as a single parent. I also agree that children raised in single parent households can turn out fine. For that matter, I was raised in a single parent (mother) household from the age of 7 years on and think I turned out okay (no comments from the peanut gallery about that, please). I also don't want to force women to stay with men who are bad for or to them simply to avoid being a single parent.
On the other hand, I don't think we can just flippantly say that single parenthood is just as desirable as, for lack of a better word, double parenthood. The influence of a father who is there for his child is a good thing. Also, look at the comments from neon88 to the same post. He writes that 60% of the births in his hospital are out of wedlock. A father has two babies in the hospital at the same time with different mothers. An 18 year old mother has three kids by different fathers. Like many neonatologists, I have seen the same things. The only difference is that in our hospital more than 90% of the births are out of wedlock, and in at least half of them there is no real relationship between father and mother. The disconnect between marriage and parenthood, even the disconnect between a long term relationship and parenthood, is complete in this subculture.
We should not discriminate against single parents and their kids after they are born. However, I think people would do well to try a little harder to prevent single parenthood by doing two things. One, be a little careful about people with whom you sleep. If they aren't someone who you would like as a parent to your child, think twice. Two, especially if you are not going to do number one, use effective birth control. It's not that hard; it's the responsible thing to do. And don't accuse me of being sexist; I think men should do this as much as women.
Like most NICU staff, I love the babies I take care of and only want the best for them. Should we treat them worse if they have a single parent? Absolutely not. But should we do everything to optimize the environment they are raised in - which includes advocating for responsible, "double " parenthood? Absolutely.
