We live in a developing country, which means that we don't drink water from the tap, which means that there is no potable water at the Bambina's school, which means that she has to bring a bottle of water with her every day to school.
So the question is, which kind of water bottle should she use?
This question is also relevant for globetrotter families who are on the go and want to have one or more bottles of water on hand for the kids.
One obvious answer is your standard disposable plastic bottle of Evian or other bottled water. But they get grody after a while and they are difficult to wash. Plus have you ever looked at the water inside a bottle of Evian after your child has drunk from it? There are food particles in it because kids backwash.
Another possibility is a hard plastic bottle like the kind you can buy in our local Jumbo grocery store here. The Frenchman bought one of these for the Bambina last year and I nearly had a keniption. Besides the fact that your water ends up tasting like plastic, the bottle itself was made in China, reeked of "new plastic" and was probably leaking polyvinyl chloride and/or Bisphenol A into the water. That and the fact that it leaked all over and broke after about two weeks of use meant that we had to search for another bottle.
Aluminium cans with a lining, such as a the famous Sigg line, come with concerns about what, exactly is in the lining. Sigg swore that the lining in their water bottles contained no Bisphenol A - until they changed their minds and admitted that all bottles sold before August 2008 did have Bisphenol A "but only in tiny amounts". Great.
Rather than worrying about what may be in the lining of an aluminium bottle, you can always get a stainless steel bottle instead. Stainless steel is made of chromium, iron and nickel. Stainless steel bottles don't generally have lining inside, as stainless steel doesn't leave a metal taste in your month and there is no danger in ingesting the molecules (iron is good for you!). There are a few brands out their but we bought the Crocodile Creek brand at Le Bon Marché department store in Paris.
