Eph:  Momma, where does your boob milk* come from?

Me:  Where do you think it comes from?

Eph:  Well.  ((very seriously))  First I think when you drink some milk, the milk goes into your tummy.  Then it goes on a conveyer belt, then it goes on another conveyer belt.  Then it goes in a pool, then in a tube, then in Talya's tummy, then out Talya's bum!

He's going to be a doctor, I tell ya.

*yes we do call breast milk 'boob milk'.  Gotta problem with that?
