I have never been told not to sterilise bottles etc, I have heard this through friends but for me I just couldnt not do it, I chose to sterilise untill all my children were atleast 1 year old, and if I were to have anymore I would also do the same again, I know when I was in hospital with my youngest, they used disposable bottles but they also had an avent electric steriliser to use if you had bottles to do or anything else, they obviously still expected that people would do this.

also I totally agree with Snacks here too

Milk products contain heaps of bacteria, and they'll breed in the little spaces in the teat and bottle, so IMO it's worth sterilising items you use for milk.
