"Quiverfull"?

I had noticed a lot more large families at the churches I attend and visit. Whereas one day four kids was a lot, nowadays at many churches you see families of 7 or 10. I thought it was interesting, but apparently it is a movement. Who knew?

The movement, called Quiverfull, is based on Psalm 127, which says, "Like arrows in the hands of a warrior are sons born in one's youth. Blessed is the man whose quiver is full of them."...The Swansons subscribe to the Quiverfull movement.

"When we first got married, we actually didn't want children," Kelly's husband, Jeff Swanson, says.

But then the Swansons began to notice that the Bible was very high on big families. And Kelly says that she and Jeff decided that God knew how many children they could handle.

"We just started thinking, 'God is sovereign over life and death. God opens and closes the womb,' " Kelly says. "That's what his word says, so why we're trying to fiddle around and controlling ourselves, we need to stop doing that."

Honestly, I find the idea a bit strange, although I know this kind of thing was the norm only a few generations ago. My grandfather came from a huge family... but only a small number made it to adulthood. Is this a reaction to the overpopulation mania of the 70s, or a real Biblical idea?
