April 10, 2014 -- Jill Duggar and Derick Dillard are waiting until their wedding to share their first kiss -- but they're already talking about having kids.
The "19 Kids & Counting" star, 22, and her fiancé, 25, both responded enthusiastically: "Oh yeah!" when asked if they want to have children.
"Both of us want as many kids as God will give us and we've talked about adoption," Jill told ABC News. "My parents have kept popping them out so we'll see how [our] fertility is!"
Jill and Derick, who met last summer and began courting in November, announced their engagement on Wednesday. Jill is the first of the female Duggar children to be engaged; her older brother Josh is married with three children of his own.
For Jill, being the first of her sisters to get married is "really exciting," but also bittersweet as she'll have to move out of her parents' home in Arkansas.
"I won't be right here having late night chats with my sisters every night," she said. "But at the same time, Derek is from our area, so we'll live pretty close. We'll still get to see each other!"
Jill's mother, Michelle, added that there's no jealousy between the siblings.
"Our girls are so close... and they're not going to be disappointed if they're not in relationships because it's all God's timing," she said. "They're confident in who they are and where they are in their lives. It's really sweet!"
