Nickel allergy is a huge hassle. There are so many products that contain nickel. My son can only use nickel free products. We even cook in 18/0 stainless cookware. Items can be hard to find. We buy a lot of plastic (tweezers and stuff). We found belts (a hard item to find) at nickelfreebelts.com. It seems there is getting to be more awareness, though, so maybe we will become more like Europe where it is standard to have everything made nickel free someday.
