Children are mimics
Parents don’t need all the years of research into children and television to know that children are mimics (though they can certainly refer to that if they want). They only need that moment when their toddler throws back, ‘hey, what’s the big idea?!’ or, ‘that’s stupid!’ or some other phrase they picked up from some other child, their parent or, often, television.
So it’s a good idea not to write something in a children’s cartoon that you wouldn’t want a toddler to throw back at you. Or their parents.
Important to remember you’re reaching more than just your children.
Wish I’d really thought that through before I wrote George the Mean Yellow Dog saying, ‘I hate that’.
