I read below that you should only mix BM if it is the same temp. I'm confused. I've been pumping and just pooring the fresh BM into the bottle from the previous pump that was in the fridge. What is wrong with doing this?
I believe it creates an environment for bacteria to grow. I used to always have a bag of milk in the fridge, and pump into a bottle, put it into the fridge, and add it to the bag when it was time to pump again (rinsing out the bottle).
