The Duggars keep multiplying.
"We are so excited," Duggar, 22, tells People. "We have started talking baby names. It is one of those things that is so special, picking a name for a baby."
Duggar is the third daughter born to 19 Kids and Counting stars Jim Bob and Michelle Duggar. She and Seewald, 19, had previously discussed their intentions to adopt a child, and say they still plan to do so.
Duggar and Seewald will also send a special message to fans on Tuesday's episode of 19 Kids and Counting (9/8c, TLC).
Earlier this month, Jessa's older sister Jill gave birth to a son, her first child with husband Derick.
