It's Thursday, Real Kids Day here.
Watch children. Eavesdrop on their conversations--at Target, at the library, at the grocery. What emotions do you see? What kind of conflicts are there? What makes them smile or laugh? What upsets them? How do they interact with other children?
Use these observations, maybe not necessarily for specific story ideas, but to remember what it's like to be a child. And to think about what a child would care about deeply. We are writing for them. We want them to find our stories fascinating.
Here's a little brother interaction to watch off YouTube. How about thinking up a story about siblings?
