Question about storing pumped BM

I wouldn't think you would want to combine fresh milk with frozen milk because you are not supposed to thaw and then refreeze milk. The fresh milk touching the frozen milk will decrease the temp of the frozen milk. Not sure if it would actually hurt, but it is probably not the best idea. Have you tried storage bags? At least you are only storing the size of the milk collected. I have also heard of people freezing milk in an ice cube tray and storing it is a freezer bag. This might work for you because you are pumping small quanitities at a time. As far as the freezer door. It is okay, but less stable than further back only because the door is most frequently exposed to light and temperature fluctuations. The temperature of the milk is therefore changed and, in theory, it is not able to be frozen as long. The colder the temp, the longer the milk can be frozen for. This is why you can store milk in a deep freeze longer than a regular freezer.

What kind of pump are you using? It is possible that you might yeild more milk with a different pump. Additionally, the time of day makes a difference. Most people pump more first thing in the morning than any other time.
