When a Georgia police officer responded to a 911 call of a choking baby, he had no idea just how much the moment would change his life. After Officer Kenneth Knox saved 2-month-old baby girl Ma'Yavi, her grateful parents asked him to be her godfather, an offer he gladly accepted. "We've gotten really close," Officer Knox told InsideEdition.com. "I'm going to watch over her for the rest of her life because she's in my heart now."
