Hi I'm really confused about which steriliser to get! I have been told to try and get one which will clean 8 bottles at a time, and fits other bottle brands. I'm looking at dr brown and avent bottles as i hear they are better for minimising wind. I'm also going to try and use the medala breast pump. However the matching steriliser reviews I've read aren't all that great! Please can you share your experiences and recommendations?
