DO NOT let the baby grab a poopy diaper while you are changing him.
He will get poop all the way up his back, on his hands, and everywhere else. Also, he will not stop squirming to let you clean him off and this will most definitely happen when you do not have time to bathe him.
2 hours later at work, you will find poop under your nail. Yum.
You're welcome in advance. ;)
