The Duggars Welcome Their First Grandchild!

Joshua Duggar, the oldest of the Duggar children, and wife Anna have welcomed their first child!

Mackynzie Renée Duggar was born at home with the help of a midwife, doula and her proud new father: “Josh was excited to participate in the birth as well,” a friend of the family tells PEOPLE. “They are both so happy.”

Josh, who was the one to read the pregnancy test to his nervous wife, has been very attentive throughout Anna’s pregnancy: “I ask Anna what she needs,” he told PEOPLE in July. “I talk to the baby and we involve her in our conversations. When Anna and I are talking to each other, we’ll say, ‘So, how do you like that, Mackynzie?’”

Baby Mackynzie - who is named after a combination of Josh’s cousin (Mackynzie) and Anna’s middle name (Renée) - is the first grandchild for happy grandparents Jim Bob and Michelle Duggar who are already parents to 18 children and are expecting baby no. 19 this spring.

Josh and Anna, who were married in September 2008, announced their pregnancy in April.

Congratulations to the ever-expanding Duggar family!
