> Netherlands we have the world's cleanest tap water. Eh? Dutch tap water is fine, but do you have a citation for that? Also note that "clean tap water" is a bit of a fuzzy non-metric. I live in Amsterdam[1], where the pH of water is around 7.8, but H^2O would be 7.0. So the water can be trivially he demonstrated not to be "clean", otherwise the pH value wouldn't differ. But of course what people usually mean is "has bad stuff in it", not how far it is from being chemically pure. > my wife can't stand the tap water here. Yeah, I also don't like it. I grew up in Iceland, which has particularly "dirty" water, but it's the "good" sort of "dirty", i.e. minerals and the like. That and other things contribute to taste, also temperature, Dutch tap water is too warm for my tastes. I'm not right, nether are you or her. It's just an acquired taste. > The baby bottles are all plastic. Glass is available but they're hard to find They're quite easy to find? Search for "glazen zuigfles". But... > our baby only likes one particular brand of bottle, refusing to drink from others. ...ah, that might be, i.e. perhaps it's just that manufacturer. Also are you looking for 100% glass? Usually the fitting to close it and the "nipple" itself are plastic/rubber. > My son's children's water bottle is plastic. I've never seen children's water bottle not made of plastic. Frankly I'm not sure what to do here. Get him a stainless steel water bottle, my kids have that (I'm not paranoid about plastic, but it's a more durable bottle for school). Blokker, IKEA etc. sell these. > I'm going to replace all the food containers with metal or glass soon[...] Respectfully, I think you're going a bit off the rails here, there's probably 10 much easier things you can do to marginally move the needle further on your family's mortality, e.g. applying sunscreen consistently. But just to feed your paranoia a bit: some things that are "metal" are really just epoxy, e.g. aluminum cans are just epoxy "bags" surrounded by aluminum walls. Food grade stainless steel is almost always "pure" though. 1. https://www.waternet.nl/service-en-contact/drinkwater/waterhardheid/ https://www.waternet.nl/service-en-contact/drinkwater/waterh...
