Reality TV parents Michelle and Bob Duggar changed the name of their TLC show to 19 Kids and Counting this week to include the little newest addition to their ever-growing family, Josie Brooklyn.

Josie Brooklyn Duggar was born extremely premature on Dec. 10 and has spent much of her young life in the hospital. According to her parents, she’s a miracle:

“Doctors tell us, ‘never trust a preemie,’ because you can’t know what is going to happen,” Jim Bob Duggar told PEOPLE. “It is a very day-to-day thing. It is the hardest thing we’ve ever been through.”

The Duggars will return for a new season next month.
