How come if Pebbles was born in 1963 (airdate time), can she be a teenager by 1971 (airdate time). Chronologically, she would have to be at least 8 years old, if looked at it age-wise. Not even 8 year old had curves (despite the trend in America for underage beauty queen pageants).
H-B execs must have picked it up eventually, but by the time Pebbles and Bamm-Bamm did mature, the continuity was out-of-whack by showing later Flintstones shows with the kids looking different than they were in '71.
I don't know when the marriage of P and B-B was shown, but hopefully the time lines were put back on the correct track.
Sorry to be picky, but i guess the kids (who watch the cartoons)wouldn't pick up on the continuity errors.
