I agree with the Neosporin advice, but I also have to agree with the mommy from a few posts ago... If the ear is really that irritated and causing the child pain, she should take the earring out. No 4 month old really needs their ears pierced. Punching holes into ones body is a decision that should be made by the person whose body is being damaged. And no 4 month old is capable of chosing or understanding earrings. Don't get me wrong, I love my pierced ears... But I wouldn't chose to pierce my child's body without their clear understanding of the piercing.
