Yellow

We have these little tabs that change your bath water different colors. Yesterday, I made the boys' bathwater yellow, and they splashed happily for a time. After awhile I thought I would tease Sebastian about the color of the water, so I said, "Sebastian! Did you pee in the bathtub?!" 

Without even looking up he said, "Yup." 

Well. 

I guess that was a silly question to ask a four-year-old boy, potty trained or not.
