Police Chief Elizabeth Watson gave birth Friday to an 8-pound, 12-ounce boy.

The 21-inch-long baby was born at 1:45 p.m. at Methodist Hospital, a spokeswoman said, adding both mother and son were doing well.He is the third child of the chief and her husband, Sgt. Robert Watson, who was with her in the delivery room. The couple has a daughter, Susan, 10, and another son, Mark, 5.

Robert Watson told reporters that he and his wife have yet to decide on a name for their son. "It's still under debate," he said. "We're pretty well sure, but it has changed two or three times since this morning."

Elizabeth Watson, 40, became pregnant after being named police chief last year. She is the first woman police chief in Houston and the first woman to head a major police department in the nation.
