It really does feel, partly because of graphic novels kids read, like there's a lot of freedom with how you can use both images and words, because we think in both of those ways.

I generally have an idea where I want to go, but I don't know how I'm going to get there.

With most of my books, there are some parts that pop up right away, and other parts I have to wait for.

I had read [Charles] Dickens's novels were often published serially. I thought it would be fun to write a book, just sitting down and writing a chapter every day, not knowing what would happen next. So that's how I wrote the first draft. And then of course I had to go back and make sure everything worked and change things.

It would look like a notebook with dividers, and there'd be different subjects and things [preschoolers] could do, so that they could feel like they were going to school also.

The morning time is also a time when I look at what I did yesterday. That's often a jumping-off point for today.

I think we're conditioned by watching movies.
