Hi.For various reasons had to stop BF. Am finally OK with the decision and getting to grips with formula. Not sure what is safest way to make and store formula feeds though. I use ready made cartons when out and about. At home make them up. Using Aptimil. Box says boil kettle and leave for 30 mins make up formula and use straight away. Not sure about you all but my little one is not predictable enough for that sort of schedule! How do you do it? Is it OK to make up and store in fridge? How long does the boiled water last for - should it be put in fridge?
