The baby is continually monitored by the gorilla keeper staff. She weighed 3 lbs. 9 oz. at birth and was 14" long, close to the average size of a full-term gorilla baby, according to the zoo. She was monitored overnight and the zoo's gorilla care staff bottle fed Similac special care formula for premature babies every two hours.
