We live in Central Florida and we have city water. We recently have found out that our water is high in calcium and other solids. After losing Fawn to UC I panicked about what to do. People have said that I should only give rain water or bottled water to my kids until they are at least six months old. I had a choice, I could go buy a 2 1/2 gallon bottle of water a week or get one of those filtering water jugs and just use the tap water filtered. We decided to go with the zero filtration jug. It's a little more work but they don't get any solids in the water at all with this thing and they seem to be drinking more of the water too...What are your thoughts?
