So, I only get an ounce or so each pumping session so it takes a while to get enough to put in a storage bag. So, I keep a bottle in the fridge and add the new milk to it as I pump.
Is it normal for the milk to separate a bit in the fridge? Also, I find that the milk kind of coats the inside of the bottle - it almost looks like a thin layer of egg white and when I shake it up it mixes back in. Is all of this okay?
