Conversations with the Madness Twins

Riding in the car, with my 2 year old (I) and 3 year old (R), trying to understand why my three year old has been having 'accidents' after many months of successful potty-going:

ME: How does it feel before you pee your pants?
R: when i pee my pants it feels wet
ME: no i mean, before you pee. does it surprise you or do you feel it coming?
R: my penis doesn't feel it coming
I: what I have?
ME: you have a vagina
I: my vagina not feel pee
ME: so, ronald, the pee surprises you?
R: yes
I: what does ronald have?
ME: ronald has a penis. Ronald, does it hurt when you pee?

R: no it doesn't hurt
ME: do you know why you don't make it to the potty?
