I'm being paged...
I just came back from a great conversation with the little man, which I will transcribe as he continues to sit on the potty.
Isaac: Do you want to poo poo on theeeeeeh door?
Me: Noooooo!
Isaac: Do you want to poo poo on theeeeeeh door?
Me: Noooooo!
Isaac: Do you want to poo poo on theeeeeeh door?
Me: Noooooo!
Isaac: Do you want to poo poo on theeeeeeh door?
Me: Noooooo!
Isaac: Do you want to poo poo on theeeeeeh door?
Me: Noooooo!
Isaac: Can mama say do you want to poo poo on the door?
Me (getting grossed out finally): No.
Isaac: Can mama say do you want to poo poo on the door?
Me (wondering if I should give in just to keep it from being a big deal): No.
Isaac: Can mama say do you want to poo poo on the door?
Me (giving in): Do you want to poo poo on the door?
Isaac: Noooo. Can mama say it again?
Me (grossed out after all): No.
Isaac: We don't eat poo poo!
Me (aha! something we agree on): No, we don't.
Isaac: We don't eat mama.
Me (what??): No, we don't!
Isaac: Mama's too big.
Me (well, there's some logic...): laughing, That's right!
Isaac: If we eat mama, she will stick out of your mouth.
Me (true that!): That's right! laughing and kissing that silly kid.
