Barney and Betty Rubble found a baby named Bamm-Bamm and adopted him at the end of “Little Bamm-Bamm” (The Flintstones Season 4, Episode 3), which aired on October 3, 1963, on ABC. Although Bamm-Bamm's age was never mentioned, it is assumed that he's a few months older than Pebbles since he can walk on his own.
