The Gosselin and Suleman households seem small compared to the Duggars.
The Tonitown, Arkansas reality TV family, headed by dad Jim Bob and mom Michelle, welcomed the family's first grandchild, a girl named Mackynzie Renée, who was born to the oldest Duggar son Joshua and his wife Anna Thursday.
The conservative Christian family follows Quiverfull, a movement that places added weight on the bible's demands to be fruitful and multiply (We'd say they're doing a bang-up job of it).
In an interesting twist, Mackynzie Renée will meet one of her aunts next spring when Michelle gives birth to her 19th child. The Duggars other children are Jana and John-David, 19; Jill, 18; Jessa, 16; Jinger, 15; Joseph, 14; Josiah, 13; Joy-Anna, 11; twins Jedidiah and Jeremiah, 10; Jason, 9; James, 8; Justin, 6; Jackson, 5; Johanna, 3; Jennifer, 2 and Jordyn-Grace, 9 months.
18 Kids and Counting airs on TLC; a special chronicling Mackynzie's birth, First Grandduggar, airs Tuesday, Oct. 13 on TLC at 9/8c.
