Everything a child learns comes from information that is beyond their understanding. It's true for their first words, even from what we call "baby talk." It's certainly true for concepts related to diplomacy, economics, and music theory. I never talked down to my kids. Maybe that was good, effective parenting, and maybe it presented problems for everyone else in the family. Hard to say. It did raise questions, though, and anything that leads children to ask clarifying questions is probably great for their intellectual development.
