If you find yourself tempted to present a lesson, or to teach, feel that feeling and refrain from it. If your child asks a question, just answer the question. Answer it in an interesting way if you can. Look it up if you need to. Don't turn it into "a lesson."
If a child asks a question he might ask another one. Be prepared for one question to turn into fifteen of them. Be prepared for it not to.
