With the birth of their newest grandson, Michelle and Jim Bob Duggar are over the moon. They took to their blog to gush about Israel David Dillard, Jill and Derick Dillard’s first child.

The 23-year-old 19 Kids and Counting star posted a video message introducing their son on Tuesday after she gave birth on Monday night.

On the family’s blog on Tuesday, the Duggars gave an update on how Jill is doing and how Derick, 26, is handling being a father for the first time.

“Our sweet new grandson, Israel David Dillard is here. We love him so much already and we love his name!" they wrote.

"Our Jill is doing wonderful and Derick seems to have a permanent smile on his face now! Israel is precious and his arrival is just another reminder of how very precious life is and how every child is a gift from God. We are happy grandparents!" the couple continued.

They will become fifth-time grandparents soon enough, when their son Josh Duggar and his wife Anna welcome their fourth child.
