One...I have a LAZY eater and latcher...but I so badly want to be able to breastfeed but it seems my LO just prefers the bottle. Anyways... I'm desperately trying to build up a supply and hoping to continue to breastfeeding but really it doesn't seem like it'll happen..

I have a Spectra S2 and double pump for 30 minutes every 2 hours...or just recently started that. What should I do to increase my supply? What is power pumping? All advice and information on what I should do or expect would be amazing. I really don't want to supplement with formula but if need be then...so be it. We do use a bottle at night but that's simply to introduce it and have him get used it.
