BF help ftm

I was reading stories on babies who wouldn't or couldn't latch. my main question I guess is, if that happens to my LO, I can still pump throughout the day and just give him the BM out of a bottle. What kind of bottles do you recommend? I know moms who boil their nipples to the bottles, is that something you're supposed to do (sorry ftm) 

I'm just trying to prepare myself as much as I can before my son arrives in a few weeks.
