Im Just a new mum and for the last couple of day have been using the pre made milk but im wanting to switch to powder. If i went by all the rules on sterilising and preparing i think i would have a very unhappy life with a screaming 5day old and spending my whole day in the kitchen. What i want to know is do you sterilise your bottles one at a time and make a feed when there screaming? Or do you prepare them in advace? My friend suggested sterilise bottles and put fresh boiled water in them and add the powder when i need it. What do you think?
