Gee ... what could he be smiling about? How about the fact that despite my best effort and using a cloth diaper the size of Texas he always spits up on me. You can have your whole shirt nicely covered with the cloth diaper but guess what!! He will never spit up there ... no he would rather spit up on your nice clean shirt or pants, ya know whichever he can get too. So he's happy to spit up on me! You just wait little man!
