I grew up thinking babies came from their mommy's belly buttons! I literally thought your belly button would get big, the baby would crawl out, and then the baby would forget how to crawl again lol.
I was 12 or so before I had the "talk" and learned the truth.
My mom and husband still pick on me about this.
