For those of us who have not seen “19 Kids and Counting“, we are unfamiliar with the possible madness to live in a house with the Duggars and their 19 kids.

Surprising enough, Michelle Duggar claims that it’s all manageable. “We all work together, it takes everyone helping,” Michelle tells the Today show.

The Duggars run their house like a well-oiled machine. They have a total of four bedrooms and nine bathrooms. Nine girls share a bedroom while nine boys share another. As for household chores, it is non-stop and work is split among all kids (except for the baby).

So for the main question: how much does it cost to feed 21 people? Surprisingly, their grocery bill is a paltry $3,000 a month!
