The oldest of the Duggars’ 18 kids is starting the next generation. Joshua, 21, recently told his wife—too nervous to read the test results herself—"You’re going to join the Mommy team," he tells People. The pregnancy will be documented on the family’s TLC show, 18 Kids and Counting. “If they have a boy, they’re welcome to name him Jim Bob,” says Joshua’s dad—also named Jim Bob. The baby is due in October.
