With the latest addition, the Duggars’ 18 natural children range in age from 20 years to 1 day old. Included in the mix are 10 boys and now eight girls — Joshua, twins Jana and John-David, Jill, Jessa, Jinger, Joseph, Josiah, Joy-Anna, twins Jedidiah and Jeremiah, Jason, James, Justin, Jackson, Johannah, Jennifer and Jordyn-Grace.

With two sets of twins, Michelle has gone through 15 pregnancies that ended in 13 natural deliveries and two Caesarean sections.

Both Michelle and Jim Bob — a former state legislator who served in the Arkansas House of Representatives — are real estate agents. They claim their family is debt-free, with the entire bunch helping to build their 7,000-square-foot home in Tontitown. And they are enriched by a devout faith in their religion.
