Fresh bottle every feed? How do you do yours?

[Jelliebaby]

I have a two week old baby and have been advised to make a fresh bottle every time she is due a feed. She is unpredictable at the moment as to when she wants a feed so boiling the kettle and letting it cool for half an hour is proving to be a nightmare with a screaming baby.

Just wondered if anyone had any tips to make life easier? I am making up 2 bottles at a time at the moment and putting one in the fridge.

Just have half the amount of the boiled and pre-cooled water in the bottles in the fridge, then top up from kettle and add formula each time. Or even the full amount of pre-boiled that morning water, cold in the fridge then microwave it?
I really don't think it's about the water being fresh that second, it's about when you add the powder surely?
