The Duggar Family

As if Michelle and Jim Bob Duggar didn't have enough birthday presents to worry about: The parents of 18 children are now grandparents.

Anna, wife of the eldest Duggar son, Josh, gave birth to MacKynzie Renee Duggar at home with a midwife. The littlest Duggar is 8 pounds and 19.5 inches long, according to the Today show, who made the announcement on Friday.

Michelle Dugger is due to give birth in the coming months to her nineteenth child.
