Finger painting is to be done with finger paints (and permission.) Not poop.
I just spent half an hour scrubbing poop off crib and wall (and disinfecting the mattress to boot), while Jeff (who got home just after I found the mess, thankfully) bathed Bridget (the tub is now soaking in hot bleach water so I can drain it in about 10 minutes, scrub it out, and rinse it), and got her shirt soaking (luckily for us, all she had been wearing, other than the training pants she pulled off.)
We threw out the sheet. It was already stained and has seen the births of three kids, and, well, it was such a mess it wasn't worth the work to clean it at this point. We have other sheets.
I almost took a picture but have decided that I really don't want to remember it that vividly.
Thank goodness for Lysol wipes.
Please, two year olds, give your parents a break. Respect the finger painting rules. Poop is for potties and diapers, not for artwork.
That is all. Thank you.
