Jess, this is what I do with FF.

As Madeleine is only having 5 bottles in 24 hours now (220mL per feed), I normally make them up at 9pm (just after her last feed). I pour cooled boiled water into the 5 bottles (sterilised) (200mL of water) and add in 4 scoops of formula (I use Karicare Gold Plus). That makes up about 220mL per bottle.

I put the lid on and shake them up and then put the teats on last and the lid (I have to double check that the formula is dissolved and shake some more if it hasn't - normally you can see it on the bottom if it still needs shaking).

I put the 5 bottles in the fridge straight away (but not in the door of the fridge as they don't recommend it). That lasts me the 24 hours. I heat each bottle up as I need it in the microwave and shake it up before I give it to her. It takes 34 seconds to heat it up to just luke warm...this was trial and error with our microwave initially but I always test it nevertheless!

When we go out, I put her cold bottle of milk in my nappy bag (it has an area in it where it stays cold). If she needs one when I'm out, I just heat it up and voila, she's fed and happy. I heat it in a microwave in parents rooms at shops or if I am out elsewhere, I sometimes take a thermos and a jug (but not often).

I've been doing this from 2 weeks old and she is happy and thriving. I don't mind making her bottles up at all and I find it not time consuming whatsoever. But I am sure some ladies would not agree with me!

HTH!!
