After nearly four months in neonatal intensive care, Duggar baby No. 19, Josie Brooklyn, is finally leaving hospital.
"We're grateful for the prayers of thousands," Jim Bob Duggar tells PEOPLE as he and wife Michelle left Arkansas Children's Hospital on Tuesday with Josie. "We are so happy," adds Michelle. "We are so excited, we are running on adrenaline. I have been getting into the routine of every three hours feeding, diapering and taking her temperature. We are so encouraged that she is doing so well."
