She's eating for two!

Jill Duggar and Derick Dillard are relishing their final two months before becoming Mommy and Daddy.

With her growing belly, Jill and Derick descended upon an Arkansas P.F. Chang's on Jan. 18, filling up on Asian fare before their days are overrun with baby formula and their nights become sleepless.

And don't expect the birthing to end after their first child. After all, these are the Duggars we're talking about.

The couple is even open to adopting, in addition to conceiving their own children.

Jill previously told E!, "We're open to as many children as God will give us. We believe children are a blessing from the Lord and a gift from him."

Like they say, the apple doesn't fall far from the tree.
