Where babies come from

Considering I spend an overwhelming amount of time with young children, I have come to hear many ways babies are made. Today I heard one that I thought was particularly cute. While we were discussing holiday traditions, I brought up the tradition of eating. There is a little boy in my class who is expecting a baby brother soon. When I spoke about eating, he responded as follows:

"Kind of like when my mom eats a lot. After a while it builds up and makes a baby. That's why we are made of meat. That's why the wolves want to eat us."

I don't know really where the wolves fit into all of this, but I thought it was quite hilarious that he thinks babies are made when women eat too much... just think if that really were true? I'd be having twins every 9 months!
