My older son never had an issue with nudity, in fact, he rather liked it as a small child. On day we were finger-painting, outdoors, because I'm not that stupid. It was a fathers's day card, and the paint was gooey and fun. Nick asked if he could paint himself...I said sure, and the shirt was off anyway. Well pretty soon, the small boy canvas of chest was finished, and there was still more paint left so off came the rest of the clothes...."mom, can I paint my penis", "sure kiddo". Well he had stripes on the penis, and hand-prints on the butt cheeks, swirls on the legs and a look of joy on his face. He knew his art was good...so off to the neighbors to show off....nekkid as a jaybird and covered in bright paint, ding-donging the neighbors door.
What is it about kids and water???? My kids have been soaked and muddy so many times that they automatically drop the clothes on the tile floor just inside the garage and take their nekkid bodies to bathtub.
I've also had lipstick all over the kid's face, and it doesn't wash out of curly blond hair or eyebrows easily; a full gallon of milk on the hardwood floor, ovaltine all over the pantry, powdered sugar everywhere, calls to poison control about eating crayons and chalk, which is very nasty when the results come out....there's more but I can't remember them now.
