The annual March for Babies March of Dimes event is being held this weekend in Danbury.  Sunday's event raises money to fight prematurity and birth defects.  NICU nursery graduates and their families will be celebrated with special moments during the event.  A new March for Babies Memory Garden will be open for the first time to participants.  Those who have experienced the loss of a baby can remember them by planting a memorial butterfly sign.  Registration for the March for Babies at Tarrywile Park Sunday starts at 9:30am.
