Can I make up a bottle by putting in half the boiled water (left to cool for 20-30 mins) into the bottle adding the formula and mixing, then topping up with cold tap water. (dd is 6 months so can have tap water).
Of course using the full amount of water by measuring the 2nd part using a second bottle.
The initial hot water kills off any bacteria in the milk surely.
Thoughts please - Thank you
