Step 1 : Introduction to the question "Which of these cartoon TV dads had the fewest children?"
Pebbles Flintstone is the only child of Fred and Wilma Flintstone. In 1962, during the show’s third season, Hanna-Barbera decided to add a baby to the show. Their first choice was a boy named Fred Jr. When the Ideal Toy Company heard this, company executives approached Hanna-Barbera with a proposal to change the baby character to a girl for which the toymaker could create a doll, and Hanna-Barbera agreed. Thus, Pebbles was born. They sold three million Pebbles dolls within the first couple of months.
