I love lunch time conversations with three little ones! At lunch today:
Tiana: Is there blood under your skin?
Me: Yes, honey there is blood under every ones skin. That is why, when you get hurt or scratched sometimes you bleed.
Camden: (puzzled staring at his apple... a bit horrified) There is BLOOD under the skin.... ON MINES APPLE!?!
Me: No silly, not under the skin of your apple... under the skin like on your hand.
Camden: (looks at his hand which is covered in ketchup) *giggle* No Mommy, that's not skin that's KETCHUP!
And I give up... there is no use trying to teach anatomy at the lunch table to a two year old!
