Diluted vinegar is miraculous; can't guarantee it will not burn his eyes; get someone to help so that you can bend his head backward and keep it out of his eyes. Last time that happened to me with my twin girls I discovered that one had found a pencil and was "writing" on my antique Stonleigh mahogany dinner table, so don't feel bad about a diapers & wipes. I see what I have to look forward to already. I have twin 4 yr old girls and twin almost 1 yr old boys. The boys are much more routy and trouble-making than the girls ever were. I don't really dare to leave any of my children alone very long.
