I am a first time mum and wanting to buy a bottle steriliser. We have been gifted some mam bottles already. Ideally, I want to try and breast feed but will use bottles if I can't or am unable to do this. I have seen the MAM steriliser and bottle warmer together, is this worth it? Or do I get a separate steriliser and bottle warmer. There are so many brands and so many types I feel clueless. Do I go for steam, microwave, uv, cold water. Any advise would he appreciated.
