He totally knew he was in trouble, lol.
It was latex based paint, but water didn't get anything out (I think maybe it was too dried into his hair by this point). I tried Chris's shampoo, waited 10 minutes, then rinsed it out (Googled that), and that didn't work. I tried peanut butter, because that gets gum out of hair, right? I left the peanut butter in for about 20 minutes, and by that time Chris was home, so he held Carson down, in the tub, while I rinsed his hair. We were both able to get the paint out, that didn't rinse out, with our fingers/nails. For over an hour I thought I was going to have to cut his barely existent hair, and I was going to cry!
