This morning when I was getting her dressed, my daughter told me “I tinkle in my pull-up.” 

 Me: “Where are you supposed to go potty?”

Her: “In my pull-up.”

Me: “No, you’re supposed to go in your big girl potty.  Where are you supposed to go potty?”

 Her: “In my pull up”

And I wonder why potty training her is a losing battle.  Everyone tells me she’ll figure it out eventually.  She’s definitely got my stubborn streak, her brother was trained by the time he was 2.
