Cavities?!?!

Yesterday we noticed dark spots on the back of Squeaky and Blondie's lower teeth. Our first thought was "Oh no! They have cavities!" We tried to figure out what we had done wrong. We started brushing their gums and teeth at 6 months. We didn't let them go to sleep with a bottle. Any fruit juices were watered down before they received it. We had been following all the rules that we knew. How had this happened?

We called the pediatrician's office and they recommended a pediatric dentist. We called and made an appointment for today. Our fears were put to rest when the dentist looked at their teeth and told us the spots were from all the iron in the formula. Whew! What a relief. Then we started wondering why someone hadn't mentioned this to us before. It would have been nice to know that the iron-rich formula could have been the problem instead of jumping to the conclusion that they had cavities.
