Breastfeeding & Pumping

Hi Mummies, Im currently in 30wks plus and have been reading up on breastfeeding and pumping. Am a little confused about how the whole thing works. Im planning to latch and pump (so that husband can feed too) so that baby gets breast milk (hopefully supply is enough). Hope to get some enlightenment. 1) when should I pump or latch? 2) after latching, i should still pump? Would baby have emptied it? 3) how is a typical or rough schedule like for latching and pumping? 4) how long should each pumping session last? 5) how long should baby latch for? 6) If latch, latch on both breast each feeding or alternate breast on alternate feeding? 7) if pumping, pump both or one breast? 8) understand that when baby latch, there will be some leaking too. I got the haaka pump to collect if need. After collecting the milk, transfer it for storage? Sorry for the so many questions. TIA!
