So we've been sterilizing our bottles with a microwave steam bottle sterilizer. Is this at all required? What risks might exist if we don't bother?

Babies take a while to build up resistance to infection, so sterilising bottles, at least for the first few months, is definitely recommended. Milk is a very good food not only for babies, but for bacteria so you want to get bottles clean, and then sterilised!

No, it's not required. Lots of children are born into dirty surroundings and still survive.

Yes, it's advised for newborns and infants because they have not yet built up enough immune resistance. Baby bottles, teething toys, and other objects that the newborn/infant puts in the mouth can be sterilized to reduce any unnecessary burden on the child.

Once the kids start sucking on all kinds of non-sterilized toys, non-toys, stroller wheels!, etc. you can stop sterilizing.

While you are still sterilizing, be sure to read and follow the instructions carefully. It's very easy to contaminate a newly-sterilized set of bottles with a thoughtless hand movement.

PS: When we were expecting, we were lured into the fear trap and bought a brand-new Philips sterilizer. We could probably have found the same used for much less, or even a kit that can be used in the microwave like you mention. Fear can help people open their eyes and do a little basic research (good), or it can sucker them into spending more than they have to (silly).

On a daily basis, sterilization is not necessary, particularly if these things are washed with soap and hot water shortly after use.

However, when someone in the home gets sick, the bottles, nipples, pacifiers and mouthy-toys should be sterilized. Also any items left unwashed for a while (like the pacifier tied to the stroller) could use sterilization from time to time.

It was easy for me to sterilize because we had an electric dishwasher, which gets hot enough for long enough to kill bacteria. We put the nipples and small items in a special basket, and it worked like a charm.
