My youngest son just turned one. In a couple of his teeth he has cavities forming. He loves to nurse and we don't feed him sweets. Could it be the breastmilk or maybe I'm not taking in enough calcium for both of us? I'm afraid that if I take him to a pediatric dentist that will try to talk me into getting procedures done that I don't think he's ready for yet. Has anyone else had this problem and what did you do?
