Bottle feeding basics

Laura
Hi ladies im 33 weeks and planning some shoppig at the weekend for the last few bits that ive been putting off the most..... The feeding things! I plan to breastfeed, but in case i struggle want to have in the basic bottle bits also. Everyone i speak to, every ante natal class i go too and every website iv read suggests different products i need to get. Anyone havea definitive list of absolute basics i should make sure i have in should breastfeeding prove trickier than it looks!? Thanks!!!
