We knew we would eventually face this situation, we just thought it would be with Emma first but we were wrong. Tonight Eva Grace was in our bed watching a movie. The way our newly positioned bed is you can see our bedroom bathroom from our bed. Burt forgot this and went to use the bathroom. As Eva Grace figured out what he was doing (peeing standing up) she curiously yells to Burt, "Daddy, how do you do that?" Burt, realizing she can see him, responds, "practice and magic." That answer was sufficient for now but I'm sure I will have related stories to share as soon as she decides to "practice" or tells Emma what Daddy was doing.
