Can anybody tell me what the latest procedure is for making up formula? Are we supposed to make them up as needed? Have a baby starting soon who's parents want to make all the bottles needed for the day at home for me to store in my fridge but I read somewhere that this isn't best ptactise. However if parents really want to do this, if I ask them to sign a disclaimer saying that they're happy to do this and it's their own choice etc then is this ok? (should know this but haven't looked after a bottle fed baby for eons!).
