Duggar Family Expecting 20th Child -- Counting Diapers, Birthday Candles, And More

Looks like TLC will have to change the title of their hit show "19 Kids And Counting" -- Michelle Duggar is pregnant with number twenty.

After Duggar, her husband Jim Bob and 18 of her children (her oldest was absent) announced this on the "Today" show we had several questions: Can a woman's body sustain 20 pregnancies? Does every child really get the attention they deserve?

But, perhaps more pressing: How much toilet paper does that family go through? And, how often do they have to sing 'Happy Birthday'? We ran the numbers.
