Baby Josie arrived at 7:25 a.m., weighing 8 lbs., 8 oz. at birth.

"We could not be more in love. God is so good," Ballatori wrote on Instagram alongside a video of her cuddling with her newborn daughter. "Big thanks to the incredible team of doctors and nurses who helped us throughout our stay. We are so thankful to be home together as a family now."
