big brother

I woke up this morning to Will's smiling face in front of mine...

Will: "Mom, I have something to tell you"
Me: "what's up buddy"
Will: "my penis is getting really bigger" (grabbing onto his pee filled diaper)
Me: "...oh"
Will: "It's because I'm going to be a big brother...that's why my penis is getting bigger"
Me: ".....interesting...?!?"
