A Christmas gift has come early to a mom whose newborn was delivered in the back seat of a taxi cab with the help of four of New York's Finest.

It all started Tuesday when a cab driver speeding the expectant mom to Brooklyn Hospital flagged down two patrol officers.

The officers — Kerryann Douglass and Joved Serrano — helped catch the baby, who was born not breathing. Officer Douglas, a mother of three, cleared the baby's airway.

Two more officers came to their aid. EMT veteran Officer Hector Lugo snipped the baby girl's umbilical cord.

The proud mom and her husband immigrated from China ten years ago and have a 15-month-old son.
