A new baby is on the way for the ever growing Duggar family. Josh, the eldest son of the "19 Kids and Counting" clan, is expecting another child with his wife Anna. The baby is going to be the couple's fourth child together. They already have a daughter and two sons.

"We are so excited to announce...we're pregnant! #4andCounting #BlessingfromTheLord @joshduggar #19Kids," Anna broke the news on Twitter. "Thx 4 all the well wishes! Every life is precious & a gift from God - we're so #blessed to have baby #4 on the way! #4andCounting #19Kids."

Josh and Anna, both 26, married in 2008. His parents Jim Bob and Michelle gave him and all his siblings names that start with the letter "J", while Josh uses the letter "M" for all his three kids; Mackynzie Renee for his daughter, and Michael James as well as Marcus Anthony for his two sons.

It's an eventful year for the Duggar family. Josh's sister, Jill, tied the knot with Derick Dillard in June and two months later announced they're expecting their first child. Another wedding took place last month as Jessa Duggar swapped vows with beau Ben Seewald.
