My Nathan has some fantastic ways of expressing himself. Consider the following:
Scene One: Baby Leah is crawling on the floor. She has a cold. Nathan comes up behind her and gives her a big hug.
Me: Careful, Nathy. She's sick. She might give you her cold.
Nathan: No Mommy. Only her face is sick!
Scene Two: Driving anywhere in our big, comfy van.
Me: Yes, Bubba?
Nathan: Mommy! What if you were climbing a mountain and there was lots of snow and hills and rocks and there was a big monster like on the reindeer movie and he had lots of teeth and he was going to eat you up?! What if, Mommy?!
Me: Um...I would be scared.
Nathan: What if you didn't have any legs?
