Duggars...20 Kids and Counting?

MICHELLE DUGGAR, from "19 Kids and Couting" on TLC, and her husband Jim Bob announced that they are expecting their 20th child on the "TODAY" show this morning.

Michelle said that she's over her first-trimester morning sickness and her cravings include dill pickles.  She said her doctors have given her the green light for this pregnancy, and so far she hasn't had any health worries. 

The Duggars' 19 children range in age from 23 years to 23 months.  They are: Joshua, Jana, John-David, Jill, Jessa, Jinger, Joseph, Josiah, Joy-Anna, Jedidiah, Jeremiah, Jason, James, Justin, Jackson, Johannah, Jennifer, Jordyn-Grace, Josie. (Aren't they running out of J names?)

The season finale of "19 Kids and Counting" airs tonight on TLC, and you can catch a special on the family's travels to Scotland and Ireland on Sunday on TLC. (Today)

Do you think it's great that they have such a large family?  Or do you think they are doing a disservice to their kids by having so many?
