DC4 is about to be bottle fed (at least some of the time), for many reasons, including my sanity and letting my 3 older DCs feed and help!
DC2 and DC3 were bottle fed at some point, but when I purchased Hipp today, everything (as per bloody usual) instruction wise, has changed. We used to, if I recall, store the bottles with boiled water, in the fridge for up to 24 hours. We used to add the formula to the cold bottles then heat in jug: why is this apparently not a good idea anymore? 
Also, I have dragged myself into the new world and am now an owner of a microwave: I have read how you're not supposed to heat babymilk due to hot spots: surely shaking it would sort this potential hazard?? And if you do decide to heat bottles like this, do you have to do it with the lid off??
Sorry to sound so thick: new fangled etc, but cannot be arsed with waiting an eternity for bottles to heat with screaming baby..
Any road, what I need to know is, is my 'old ' method of storing boiled water, then making feeds up from cold and heating, so bad now? And what in the name of Cod am I doing about microwave heating regarding keeping lids on etc? I have heard that liquids can 'carry on' heating even after the beep?? Help an out of touch mother purleeaaassse!
