I'm two weeks PP and I'm exclusively pumping, but I've noticed a decrease in my supply the last few days. When my milk first came in, I was pumping 5oz off each breast every 3-4 hours, easy. Now I'm getting 5oz between the two. I suppose I haven't been drinking as much water as I was, so I'm definitely drinking more to help. I had started freezing it cuz I was producing so much and want to continue with that. So I'm looking for other tips to help increase my supply!
