2 year-olds are amazing!!!

So I've been teaching Joshua to cover his mouth when he coughs. I don't want him to cought into his hands because of germs, so I teach him to cought into his elbow. Thanks to the Wiggles (Song "elbow to elbow..."), he knows quite well how to curl his little arm up and get his elbow close to his mouth. Well, anyway, after nap this afternoon I had him on the changing table checking his diapers. My elbow was close to his head. He gently took my arm, placed my elbow to his mouth and coughed on it!!! I thought I would pee my pants I laughed so hard!!!! He said, "I tuse (use) your elbow, Mommy. Tank-chew!!" The mind and action of 2 year olds are just so dang amazing to me:)!!
