i thought u can keep it in fridge for 48hours tho??
I normally put them all in the fridge seperately and keep then in the fridge for a maximum of 48hrs from the time I expressed the 1st milk. I just then mix them together when I need them and warm it up.
If I do mix them though I put the one I last expressed in the fridge to cool for about 30 mins then mix them![]()
