Lesson in Child-Rearing

I learned a crucial lesson in child-rearing yesterday: if your child has been showing interest in looking at his poop every time you change a poopy diaper, do NOT, under any circumstances, let him walk around the house in a diaper.
Here's what will happen: said child will poop in his diaper, then swipe some of his poop onto his finger to look at it. Then he will sneak off to the bathroom and wipe the poop on the toilet paper, which he will leave on the roll. Then you will change his diaper and say, "yuck," and he will say, "is it diarrhea?" and you will say, "no, it's just bright green," and he will say, "I just wiped my bright green poopie on the toilet paper."
After you change his diaper and wash his hands and your own, you will discover that he did, indeed, wipe his bright green poopie on the toilet paper, which is still on the roll in your bathroom.
You will be extremely relieved that you found the poopy toilet paper before you used it, and you will learn not to let your child, who has been showing interest in looking at his poop, run around in a diaper.
