I've bought some powder, I didn't use it for ages as I'd heard that 20% of powdered milk is contaminated with salmonella - SORRY if this is incorrect - but just wondering what stage of latest instructions make the milk safe. Using hot water? Does this mean it's pretty much impossible to make a bottle up at short notice ie in the middle of the night? What is the best thing to do when you're in a hurry and haven't got 30 min to wait for kettle to cool, then to cool bottle? DD is very random with feeds at the mo and we're throwing a lot of formula away, thought I'd go for cheaper option with powder but am scared to use it.
