Can i mix new breast milk with milk i expressed earlier in the fridge?

[lollyheart]

Ive got a bottle of ebm in the fridge i need to express again can i mix the 2 together?

I think you can but only once you've chilled the second lot. IIRC they need to be at the same temperature before you mix them

yes, but I wouldn't mix them until you are ready to use: the older milk will dictate how long it is good for. I would be tempted to make 2 bottles: one of the old milk and one of the new and have a system where you know which o end the oldest iykwim
