When breastmilk is refrigerated , do you have to shake it when you want to use it like a few days after ?
Yeah shaking can denature the proteins and damage the cells. So swirling is best. I just do it under running hot water :) @burgescd
yes, to mix the fat back into the milk. I was told to swirl it not to shake but I don't know what difference it makes.
Don't shack stir it gently
