We seem to have power surges in our house, so everytime I warm Emily's milk in the microwave it takes a different amount of time! It's really annoying. I always do it 10 mins before her feed incase it ends up too hot and needs to cool down again. I usually do 45 seconds for a 6oz bottle, then sometimes it needs another 5 - 10 seconds (and sometimes it's too hot!)![]()
