While my mom was baby-sitting Staley and Adelie the other day, she and Staley had this conversation when Staley woke up from her nap.
Staley: "I have pee pee in my pants."
Grammie: (reassuringly) "That's okay. You are wearing a pull-up."
Staley: (long pause) "I have a good idea. We could pretend we are cats and my bed could be the litter box."
I'm glad they decided not to play that game!!
