Mummies who do power pump, in between the pumps, do u store the bm u pumped out in fridge or just leave it out to mix with the next pump session since its only abt 20mins difference? Can anyone share how u do it?

U have to see how long is the milk going to be staying in room temperature for because best not to stay in room temp more than 3-4hrs counting from the first pump. I more particular - so I just all put in the fridge

After I pump, I leave it in the bottle, then continue pumping 20 mins later into the same bottle. Sometimes even aft an hour later.

I just leave out. 20 mins is just fine

I mixed with the next pump
