How to respond to people who think writing books for kids is a warmup act

I stole this from my friend Kerry's blog (visit her at Windmill Watching). Thanks, Kerry! This says it as well as anything I've encountered.

“Many people believe that authors of children’s books eventually ‘graduate’ and go on to write books for adults. That’s like saying your pediatrician may get good enough to, one day, be a doctor for grown-ups.”

from Joy Feldman, author of The Gollywhopper Games

What Kerry said

Take a look at the third comment under my previous post. It comes from Miss Provo's sister, aka Kerry.

This brings up an interesting point for discussion. When should you tell as opposed to show when writing fiction?
