Breast-feeding mom's... help

Okay im 2 months away from having my fourth son.. i was able to breastfeed with my first two but only for first few days.. my third wouldnt have it at all... but this time i really wanna try my hardest to do so. No one in my family ever has done it and i really dont know alot about it i know of course how to get baby to do it since have done that before, but once leave hospital and everything like pumping how much to do that or what.. how much breastfeed how do you save what you pump.. and what are some must needs... im very much wanting to do this with this go around and keep to it.. so any help on how to actually make it easier for me and baby would be great.
