What do Fairies. Dogs and Dragons have in common?

What fairies, dogs and dragons have in common, of course, is that they all appear in children's books. Specifically they appear in the books I'm reviewing today. But do I have to have kids at home to enjoy children's books? To review them? To write them? Or can I just relate to the kid (fairy, dog and dragon) within myself?

I suspect the answer is as long as my internal child is alive and kicking, she or he (dog, dragon or fairy) is all I need. Certainly she smiles when I pick up a kids' book...
