The latest addition to the Duggar clan — seven weeks old — is hanging in there at 2 lbs. 3 oz., but her parents say Josie’s struggle is “the hardest thing we’ve ever been through.”

The tiny, seven-week-old micropreemie born to Jim Bob, 44, and Michelle Duggar, 43, (parents of 18 other children) has finally been revealed to the world, to People magazine, but little Josie Brooklyn is still very “day-to-day.”

Josie now weighs 2 lbs. 3 oz., which is clearly up from her birth weight of 1 lb. 6 oz. on Dec. 10, and is being fed breast milk through a tube. She remains in intensive care at Arkansas Children’s Hospital in Little Rock, Ark.

“Years ago, a baby this small wouldn’t have lived an hour,” says Jim Bob, 44. “We are so grateful for the ability to help her.” Here’s hoping she continues to thrive!
