Landon's Button

So I had the kids in the tub tonight, and McKayla, as usual, likes to help clean brother.  This consists of using the "bucket" as she calls it to pour water on him.  Mom was in the bathroom with us and notice McKayla pouring the water on Landon's little boy parts.  Mom asked her, "what are you pouring water on?"  McKayla innocently proclaimed, "brother's button!"
