A much bigger deal seems to be made over sterilizing here in the UK than in the US. Personally, I don't sterilize regularly - just when I get something new, and then once in a while I'll boil a load of stuff on the stove. But mostly I just wash thoroughly with soap and water.You all are pretty thorough. I've always sterilized everything once or twice and then let the dishwasher handle the rest. After about 9 months or so I never sterilized, just cleaned the stuff.
