Where do babies come from?

Annabelle asked me the big question the other day.”Mom, where do babies come from?””From their mothers,” I replied.”I know, but where do the mothers come from?” she asked.”Oh, well, the ocean and the stars and the mountains all come together and swirl their energy and make a baby.””Oh,” she said, drawing a picture of herself standing next to a flower, “I thought they came from nurses.”
My little sister has always told me that you’re supposed to tell the biological details to children when they ask these sorts of questions. I remember listening to her tell her own preschooler, Kalvin, when he asked the same question, that there are sperms and eggs and the sperms swim up the river and joins the egg and that makes a baby. I can’t imagine my explanation was any more confusing than that.
