Yeah I clean Coops face too but no coming clean.....he didn't get tear stains until he was about 5 months....or like 4 and a half months. It started when he was teething. On side is worse then the other. His left eye barely has any tears stains but the one side where one of his teeth took forever to come out...well actually i ended up pulling it out because it was brown and he was miserable...that side teared a lot
