R — Why does my belly button look like a knot?
Mom — It’s where your umbilical cord was when you were in Mommy. When the doctor snipped it, it became your belly button.
R — You mean he knotted it like a rope?
Mom — I’m not sure he knotted it, but I know he cut it because you didn’t need it anymore.
R — Are the veins and arteries that were connected to it still in my body?
Mom — I’m not sure how that works, but I’m sure we can look it up.
R — Yeah. You probably need to do some science on that.
