How do you do this? I am a novice at bottles having just started combination feeding after months of ebf. I have been using readymade formula but it is too expensive so have bought a tub. I know the guidelines say make up each feed as you go but what about when you are out? Also need something on standby for that hungry first bottle in the morning.
Am I right in thinking I use cool boiled water in a sterilised bottle stored in fridge until needed? Then add the formula and warm?
If so, how long can you keep the bottle in the fridge and what do you do when you go out?
