My pediatrician told us that we should use tap water to make our lil one's formula because it is safe and well regulated. He said boiling was a nuisance and takes a lot of work. He also told us that regular hot water and soap is good to wash the bottles, there is no need to sterilize them.
Well, we eased up on the sterelizing and only do it once a week and only with the nipples and just wash the bottles in hot soapy water and let them air dry. So far so good. We still boil the water though and keep it in a thermos all day so it is still hot, then we use half hot and half cooled previously boiled water to make the formula.
In the states they have purified water for making formula. They are available at Walmart and Target. If you can make it across the border or know someone going ask them to pick you up a bottle. That would make it easy for you if you wanted to use bottled water. Regular bottled water I wouldn't trust for baby's sensitive stomachs.
