Just when you thought the Duggar family couldn’t get any bigger... The firstborn of the "19 Kids and Counting" clan, Josh Duggar, and wife Anna welcomed their third child to the world Sunday morning.

The couple announced on The Today Show Friday that their children, 3 1/2-year-old Mackynzie and 2-year-old Michael have a new brother, Marcus Anthony. The family of five revealed that they’re “thrilled” to welcome their new 9 lb., 3 oz. bundle of joy into their growing brood, saying, "We are so thankful that mom and baby are well! We are blessed to have our family close as we celebrate this gift from God.”

The announcement comes just in time for the June 16 premiere date of TLC’s “Kids & Counting: GrandDuggar Makes 3!” documenting the youngest Duggar family member's arrival. The young family made an appearance on ExtraTV in March to share their joy over the upcoming birth. “I feel great. This is the best pregnancy I’ve had so far,” said Anna. “We are very excited and just looking forward to our third little one,” said Josh, who said the baby's official due date was June 7.

Earlier this year the original Duggar couple, Michelle and Jim Bob, revealed that they’re considering expanding their already expansive brood of 19 biological children, the focus of the TLC reality show. “We are open to the idea of adoption,” 45-year-old Michelle told People magazine. “We are praying about it and we will see what God has in store. Love for children has been placed in our hearts."

“Kids & Counting: GrandDuggar Makes 3!" airs on Sunday, June 16, on TLC at 8 p.m. ET.
