Annually Bright Happy Power provides interactive games and activities, along with “wish bells” for patients treated at Childrens Hospital Boston, in honor of the Polar Express book that is read and the associated movie that is viewed each year at the holiday. From our modest events on oncology/hematology, this event has grown to become a hospital-wide event available to patients and families on all units with pajamas, gifts, stories, games and activities, largely sponsored by Mission One and other nonprofits.
