My breast milk came in actually the day I asked y'all about it. Some sessions are better than others. I'm still supplementing. It's frustrating because I feel so bad for baby as he struggles to latch. The Dr suggested to hand express to soften nipples...but I don't get much out and my nipples are still hard afterwards. My pump doesn't come until Monday. I only planned to do so 4-6 weeks because of my work schedule and supply anyway, but I'm already getting frustrated.
