LITTLE ROCK, Ark. -- Mother's Day draws a crowd in the home of an Arkansas woman -- she is pregnant with her 18th child.

Michelle Duggar, 41, said she is six weeks along in her pregnancy and that everything is going well.

This weekend, Duggar will join her husband and their 17 children to celebrate Mother's Day with brunch at a hotel in downtown Little Rock. Their youngest child, Jennifer, is 9 months old. Their oldest, Josh, is 20.

The Duggar children include 10 boys and seven girls. Within the group are two sets of twins.

The fast-growing family lives in Tontitown in northwest Arkansas in a 7,000-square-foot home. The children -- all of whose names start with the letter J -- are home-schooled.

Jim Bob Duggar, a former member of the Arkansas General Assembly and an unsuccessful U.S. Senate candidate, has not been specific when asked how he supports such a big family.

But he said he was guided by a seminar about 20 years ago -- a system he still advocates -- that blends finance and religion.

"The success in a family is first off, a love for God, and secondly, treating each other like you want to be treated," Jim Bob Duggar said.

"Our goal is for each one of our children to be best friends, and everybody working together to serve each other makes that happen."

The other Duggar children are Jana, 18; John-David, 18; Jill, 16; Jessa, 15; Jinger, 14; Joseph, 13; Josiah, 11; Joy-Anna, 10; Jeremiah, 9; Jedidiah, 9; Jason, 7; James, 6; Justin, 5; Jackson, 3; and Johannah, 2.
