hi i have a 2 wk old dd2 and i as i had a c-section i have been sterilising bottles and putting them in the fridge empty and using cartons of readymade formula when needed. i just wondered what was best when using the formula powder. with my ds1 i made up the feeds with formula and then stored them in the fridge, i cooled them down first in cold water. but i was thinking is it better to sterilise the bottles and put them in the fridge with cooled boiled water in them. then when baby needs a feed warm the water up in a jug of hot water then add formula powder? or will the powder dissolve in the water if it is cold? any suggestions/help please
