Hi
I currently make up bottles in advance according to the WHO guidelines - sterilise bottles, boil water, let cool to 70 degrees and then make up with the powder to ensure any bacteria in the powder is destroyed.
However, a number of people I know just make bottles of boiled water, cool it to room temperature, then mix with the powder at the time it is needed. They all seem to think I am being over the top with the way I make up my bottles and don't seem to believe me when I say I am doing it to kill any bacteria in the powder (they say "why would the formula company sell powder that has bacteria in it"?).
I'm really just looking for some views on what MN's do, and if my way really is necessary, or if it is safe to do it the other way.
Thanks!
