My wife used to watch the show until they announced they were having #19, then she stopped keeping up with it. It seems as if they have the resources to take care of them, but I don't know how much of that comes from their TV show and promotional appearances. They seem like a great family, but there's a point where enough is enough, no matter what your beliefs are. When a doctor says it's far from healthy for you to have anymore children, ESPECIALLY after having 19, I would be inclined to listen to him. Their reasoning is based on their beliefs, they don't believe in birth control or surgery to prevent birth, so they will continue to have children.
I'm fine with large families, but it just seems like they're trying to prove people wrong now, rather than simply following their faith. My wife's aunt and uncle have had 8 children and her uncle finally had to get a vasectomy after the 8th child, because they could not afford to feed anymore children, even though they didn't want it to come down to that. Each of their children are no more than 2 years apart too.
I have absolutely no problem with birth control and neither does my wife, because even though we want 2-3 children, we most certainly do not want 8 and definitely not 20... I remember the same aunt above that has had 8 children told my sister in law right after she got married "Just remember, if you use birth control, you're likely killing a child every time you are intimate with your husband..."
That's just insane. There is no reason to bring an unwanted child into this world, no matter what your religious beliefs are.
