From my reading six year molars may erupt as early as four years of age. From my son's teething history this may be applicable. As an infant he began teething at three months of age and had four fully erupted incisors by four months of age, and all twenty teeth, including two year molars by twenty-three months of age. It seems he is teething again and working on new teeth.
Anyone with experience?
