Jinger Duggar and Jeremy Vuolo only announced their engagement last month — but the former 19 Kids and Counting star’s family is already waiting for their baby to arrive!

"Derick’s bet is on Jinger! We will just have to wait and see,” she told Us Weekly.

Jill also said that she and her husband would love to give their one-year-old son, Israel, a sibling.

This comes on the heels of Jessa Duggar's confirmation that she is expecting baby No. 2 with her husband, Ben Seewald.
