I found giving an answer that has some kind of final or really helpful/obvious consequence helps a lot. A reason instead of an explanation (that's tricky, don't mock your child). Eg: Instead of: - Why does it rain ? - Well, you see, there's that thing about clouds that goes through different pocket of air and... Try: - Why does it rain ? - To make vegetables grow :). YMMV
