The Duggar family have 17 and aren't sure that they're through yet. This family from Arkansas (they father's real name is "Jim Bob" - actually James Robert, but he goes by Jim Bob) has had two sets of twins and 13 individual births.
I've seen their website, it's sure to meet the approval of my pro-life friends. In fact, you could almost say that it's pro-life to the extreme. But what impressed me was that it's not in-your-face pro-life. I got the impression that if one of their friends wanted to use birth control (they obviously don't) they would not chastise the friend.
I did some searching and found that their are some people who don't agree with the Duggars. While the Duggars won't get in their face, they will get in the Duggars' face. They argue that there are too many children starving (not these children though), that they will push their ideas on their children (isn't that a parent's job?) or that they're just weird. They also argue that it's not natural or healthy.
While I agree that they are different, I'm not sure weird fits. And as for natural, what's not natural? A child is the natural result of a healthy marriage. Sometimes it doesn't work that way, but when it does, it's a beautiful thing. The fact that they don't want to prevent childbirth just makes it completely natural.
I'm sure there's a lot I don't know, but I think this is great for this family. Congratulations to the Duggars.
* Update *
The Duggars were on NBC's Today show this morning. They consider each of their 17 children a gift from God. The background searching I did said that they own DEBT FREE a 7000 square foot home. I forgot to mention that the kids are home schooled, on the Today show was a clip of the school-teacher mom teaching bankruptcy law. All of the family looked normal, healthy and happy. My wife said "if you are really happy, you can't fake that".
Side note. We have half that many children (if you count sons-in-law and daughter-in-law).
