I have an Avent one that I used for all of DD's bottles, dummies and teats. I use it now for my breastpump and to sterilise bottles to store frozen bm in.

I've never used it to sterilise bowls or eating utensils, they go through the dishwasher and that's hot enough for those, since they aren't storing food in them for any length of time.

DS is 10 months old and I only sterilise for him still because if I pump milk I freeze it - anything that's going to be stored will keep a bit longer if it's stored in sterile containers. When DD was a baby on formula I sterilised her bottles until about 12 months but in hindsight it wasn't necessary to do it for that long.
