I'm thinking about writing a book to teach kids philosophy, but I've run into a bit of a writer's block from the onset. I'm not sure whether to start with epistemology(theory of knowledge) or metaphysics(theory of reality). At first I thought about starting with epistemology, then metaphysics, on the grounds that people base their views on reality around knowledge. But then I realized that one's understanding of reality will often influence how they perceive knowledge. Which one is better to start with? Or perhaps is starting with one or the other inaccurate and should both be introduced at the same time?

I wish you great success in this project! For inspiration, you might look at the entry on philosophy for children on the Stanford Encyclopedia of Philosophy. The books by Gareth Matthews are particularly good and are reference in the SEP entry.

I suggest you might begin with both metaphysics and epistemology. It is very difficult to do epistemology without some (presumed) metaphysical claims (there are observations / sensations / there is thinking / doubting...) and difficult to consider metaphysical claims without engaging in epistemology (what do we know -or have good reason to believe about observations / sensations / thinking / doubting). You might even begin the book with making the claim that while it is tempting to prioritize epistemology (for example) it is difficult to do without some commitments or assumptions about what there is.

One blended way of practicing philosophy with both epistemology and metaphysics can be found in the tradition of so-called critical common sense philosophy as found in, say, Thomas Reid, Bishop Butler, G.E. Moore, Roderick Chisholm.

Good luck with your undertaking!
