I just wanna cry I'm trying to increase my milk supply by pumping more so I was just pumping mind you I put my daughter to bed she was knocked out and I'm trying to get a last min pump in before bed when she decides to wake up and cry so I stop and get her only to lose some of the milk I pumped what should od been two Oz as result us one and I call my bf and he laughs and I'm like no not funny it's frustrating because he and I don't live together and my aunt already went to bed...I swear I feel like a single mom sometimes it's so hard for me to do somethings like pump cause my daughter refuses to wat from my breast I love her a ton but honestly I wish I had another me to pump and I could handle her...ok I'm done sorry for anything spelled wrong or if it doesn't make sense
