Happy Mother's Day x18

It's a happy Mother's Day for an Arkansas woman — she's pregnant with her 18th child.

Michelle Duggar, 41, is due on New Year's Day, and the latest addition will join seven sisters and 10 brothers. There are two sets of twins.

"We've had three in January, three in December. Those two months are a busy time for us," she said, laughing.

The Duggars' oldest child, Josh, is 20, and the youngest, Jennifer, is nine months old. The fast-growing family lives in Tontitown in northwest Arkansas in a 7,000-square-foot home. All the children — whose names start with the letter J — are home-schooled.

Duggar has been been pregnant for more than 11 years of her life, and the family is in the process of filming another series for Discovery Health.

The new show looks at life inside the Duggar home, where chores — or "jurisdictions" — are assigned to each child. One episode of the new show involves a "jurisdiction swap," where the boys do chores traditionally assigned to the girls, and vice versa, Duggar said.
