Meryl Yourish has good advice for those charged with changing the diapers of baby boys. Many years ago I worked with a man who bragged about his first-born son: "Not even a week old and he can pee right over the top of his head!" As I recall, he (the son, not the father) would sometimes fall short and get himself right in the face, then rub his eyes with his tiny fists as if thinking "Who did that? And why is he being so mean to me? I haven't done anything!"
