One thing that helped me as a kid was that my dad made time for us both to sit down and write a free form "story" (really a big paragraph) as kids. It could be on any topic but sometimes we'd all agree to write on the same topic if we were having trouble starting. My siblings, father, and I would all write one over half an hour, and then read them to each other and discuss them. I did fight it plenty, but in the end it was fun and helped make reading and writing more of a natural thing for me.
