Mommies help. I don't know what to do. My baby just turned 2 months. I was pumping in where between 6-7 oz at one point I needed myself up when all I was drinking at work was sodas so I stopped after I lost an oz. gained it bak after drinking more water. Well for the past two weeks I have drank nothing but water and I can barely pump 4 oz. I think working full time is taking a toll on me badly cause I can't get to pump when I need to and when I do I have to stop a few times to go deal with ppl. School isn't to bad class is only 4 hrs. I work 5 days out the week and class 2 days. I don't want the journey to end just yet.
