It was a bittersweet day. At 19 months old, Jack Shields had to say goodbye to his friends on the staff at Nationwide Children's Hospital in Ohio. Jack and his twin brother, Jonah, were born 14 weeks early with bronchopulmonary dysplasia, a chronic lung condition common in premature babies. Jonah was released from the hospital and has been waiting at home for Jack. The hospital gave Jack a beautiful send off as he headed to another facility closer to home.
