Baby Center Opened on Main Street, U.S.A. at Disneyland in July 1957, in response to requests from mothers for a place where they could change and care for their babies during a visit to Disneyland. Disneyland nurses had an unexpected event happen on July 4, 1979, when the first baby was born in the park—Teresa Salcedo weighed in at 6 lbs. 10 1/2 oz. The happy but surprised parents were Rosa and Elias Salcedo of Los Angeles.
