Most child actors, once they hit 18, once they hit 21, that's it. Even teenage kids often don't make the transition.

Unlike me, a lot of child actors are very short, which is why they work. So when they're 15 they can play 11 or when they're 18 they can play 14. They look young for so long, they have abilities a much younger kid wouldn't have.

Not a lot of people make that transition from child actor to bigger, better roles.

Most child actors go through that. Unless you can transition into an adult star, your career is over.

Child actors don't have great track records.

'Parenthood' has been the beneficiary of wonderful performances by child actors.
