Any tips?

Ca

I'm due with my second boy in September. My first also turns one in September. breastfeeding made me miserable, but pumping was fine. I was thinking about exclusively pumping for the first little while if I can manage it. Does anyone have any tips or tricks or advice/vitamin recommendations? I hate tea, literally cant stand to drink it without gagging, so that's out of the question. I would love to still get my boy his nutrition from my milk and only supplement if I have to. I have the Lansinoh Double Electric pump, if that makes a difference.
