I guess I don't have much of a choice unless I want to continuously be spending all of my money on bottled water. Our water naturally has tons of flouride in it. I run most of the drinking water thru a distiller, but it only makes a gallon at a time and takes a few hours to make.

I don't drink much water anyway. I prefer cokes. LOL!

But, I do have to mention this. My husband grew up on this water. and even though he has stained teeth, he has NEVER had a cavity. And it ain't from brushing his teeth all the time, because I have to remind him to do that. My SIL however has had cavities. The dentist thinks it was because the anti-venom she was given when she was rattlesnake bit as a toddler did something to the way her body makes enamal? something like that.

But I have only used distilled water on the babies. Since I never used formula, there was no harm there.

edited to add that I should mention that we have a well. When you are as far away from a town as we are, that's what you get. The water isn't the best tasting, so I do drink distilled, but cook with regular water from the tap. Not all the water around here tastes bad. My FIL's ranch has some of the coldest, best tasting water around. Not from a well, but from the windmills! There are stock tanks set up under the windmills for the cattle. In the summer time, we go swimming in them. Yeehaw! LOL! I don't know what the floride level would be in them.
