A baby boy making an unexpected entry into the world early Christmas morning was delivered by two police officers in Montreal. They were flagged down by the frantic father around 3am and helped the mother deliver the 32-week, premature boy in the family car, reports the CBC. They helped them keep warm until an ambulance arrived, and later visited the hospital with teddy bears for the healthy newborn and his 4-year-old brother. One of the officers says that although police learn first aid, delivering babies isn't covered. "That was all instinct," he tells the Montreal Gazette. In another surprise Christmas delivery, transit police in Philadelphia helped deliver a baby boy on the subway. (More Montreal stories.)
