Jill Duggar Dillard's son Israel David from the new TLC series "Jill and Jessa: Counting On" is such an extroverted baby that he loves being around people all the time. Dillard says her son usually has a "very sweet personality," but this changes when he's kept to himself for a long period of time.

"He loves to be with people more than alone by himself, but if he has a clean diaper and full belly, he can entertain himself for awhile," she told Us Magazine.

But after his self-entertainment has passed, Israel finds a way to convey to his parents that he is not pleased. "He has started developing a little more of an attitude recently to try to tell us when he doesn't like certain things," shares Jill. "For the most part, as long as he is entertained, he stays happy."

The young mother does not know who Israel takes after the most, but she thinks he's a little bit of both her and husband Derick. "It's hard to tell who he will be most like as a kid, but as far as a baby, I'd say he is a lot like both of us, since from what I hear we were both pretty good babies," she says.

Physically, Jill adores how he takes after Derick. She often "can't help but think how cute he is."

"I also love watching him giggle any time we tickle his belly," she says. "He has such a cute big smile with slight dimples (from Daddy!) and big baby teeth. He melts our hearts!"

Jill says she's happy they were able to raise their son in Central America because it allows him "to experience different cultures at a young age."

On the flip side, however, they can't help but miss their family back home.
