Huh?

The two big kids, G & K, are usually pretty helpful to B. Unfortunately, they also think they always have to be involved in everything that's going on with him. This morning, C was changing B's diaper and both G & K were hovering, right there in the bedroom. C asked them to leave. K said, "I'm watching so I know how to change a diaper when I grow up to be a mom or a dad." C told her that she's a girl, so she'll be a mom. G laughed. K said, "Oh.....I knew that!"
