Breastfeeding? I just found out that my son who never had any refined sugar or even juice before the age of two has like at least 5 cavities. He has to be put under so the dentist can attempt to fill them and if he can't he wants to pull them out! By the way he is 2.5 now and nurses to sleep and whenever he doesn't feel good or just needs to connect. The dentist said it could be a mixture of sugar and breastfeeding, especially at night. I was taught that breastfeeding was not suppose to do this like bottle feeding does. Anybody have experience with this?
