Children can be full of questions: "Why is the sky blue?" "What happened to the dinosaurs?" "How are babies made?"

Responses to these questions — especially that last one — usually require thought, attention and nuance. It's an important part of being a parent, but there are times when simply telling kids the answer isn't enough. Sometimes you need to show them — except, again, for that last one.

Kids want to know how everything is made: cars, buildings, their shoes, their toothbrush, and perhaps even the crackers they're munching on right now.
