Hi all, I am looking for some advice. My DD is 10 days old and I breastfed for the first week but she was losing weight so decided to supplement with formula. I feel so new and clueless about the whole process and my question this time is around MAM bottle steriliser and warmer. I think I am overthinking things but my question is, is the bottle warmer sterile if you warm up opened bottle? Am I meant to sterilise the two baskets that surround the bottle? Is there a better way of warming up bottles? I am using the ready made Aptamil formula which I don’t warm up when taken out of cupboard but once opened it goes to the fridge for up to 24hrs and that’s when I warm up bottles.
