Too much milk here too. I was pumping 50-80 oz a DAY at one point! Too much!! It gave me plugs, mastitis, etc. we had some issues because I had a lot of foremilk, would fill the bottles, and baby didn't do as well as he did once I figured out to mix the bottles which balances the fats better Better to control the OS (Lauren...you might want to quit pumping as it perpetuates the OS ) and make just what you need.
