Where do babies come from?

It's a question that as parents we know we will some day be asked by our children. The other day I was telling Pete of a high school friend who I had heard from who had just had a baby. Nick chimed in and asked "Where did her baby come from?" As I was thinking of how best to respond he continued, "Did it come from her belly or did she adopt it?" I love that he thinks that way and that we have a little while longer to answer that other question :)
