Help! Need more milk!

Cass

I decided to only pump today and not Nurse, to kind of get an idea of how much my daughter may be eating during the day. In 7 hours I have only been able to pump 12 ounces. At this rate that isn’t going to be enough to feed her for a day, as I am going back to work in a week and a half! She is 7 months. Any tips?
