Diane, I agree that it is a mixed message. I buy the non-sterile kits and tell the moms that they should sterilize all the parts. I like your idea of buying the pre-sterilized kits but many moms really appreciate it when I take the kit out of the package and show them how to put it together. I wouldn't want to do that with a sterilized kit. Patt Jamieson, LLL, AAPL Renton, WA
