I've heard that the prolactin levels naturally rise during these hours and that if you can pump or nurse during that time, it can have a huge impact on your supply. I'm wondering... If I cluster pump between the hours of 3 am and 4 am (10 min, 10 min off thing) if that would make a difference. Could I then sleep a bit longer in between or should I still get up 3 hours later to pump? I REALLY want to get more breastmilk for DS. Especially since we're coming up on him being 6 months old. Not that his age matters so much as anything else but I can only get one more month with the lactina. Then I'll have either rent one or use my PISA. I would really love for him to be on breastmilk only by Christmas.
