My 3 year old today wanting to have a conversation while on the potty:

3: Mommy what on your shirt
Me: A ribcage. They're bones
3: OH. I like bones
Me: Mommy does too... she thinks they're cool
3: I have one at home
Me: Ok. You have them in your boby
body
3: No. Not in my body. Just poop in my body
