200 and counting? Duggar parents of 19 kids expect 200 grandchildren

With 19 kids, how many grandchildren should you be expecting? About 200, according to Jim Bob and Michelle Duggar.

The couple, who is at the center of the TLC reality show "19 Kids and Counting" posted a video to Facebook congratulating their daughter Jill on her first child. In it, they mentioned their expected number of grandchildren.

"Four grandkids and counting. Going on 200," Jim Bob said, seemingly joking.

The family is well-known for their belief that they should have as many children as God sees fit. The three married Duggar children agree with this belief, and at least one, Jessa, has a desire to adopt as well.

Having 200 grandchildren would be a pretty big goal, but it is possible. The Duggar kids would need to average more than 10 children each for the grandchildren to add up to 200.

The Duggars originally appeared in several TLC and Discovery Health one-hour specials, mainly focused on an ongoing quest towards growing their family.
