When the littlest Duggar made her way home from the hospital for the first time, it was an emotional event for her 18 older brothers and sisters. Though parenting is nothing new for Jim Bob and Michelle, tending to a preemie is an altogether different experience. Josie Brooklyn weighed just one pound and six ounces when she was born at 25 weeks gestation on December 10, 2009, and left the hospital months later. She has since been readmitted, but Sunday's sweet episode of The Duggars: 19 Kids and Counting shows the family under one roof for the very first time. Will you tune this Sunday at 8/7 (central) on TLC?
