This is a conversation that took place between E and A.
"daddy? why does mommy have to nurse the baby all of the time?"
"well, babies eat a lot. Why? do you want to nurse?"
"nooooo. I used to nurse, though. did you nurse when you were a baby?"
"yep. But, I got momma milk from my mommy, not yours."
"oh. that was when Grandma had nipples."
