First time mom looking for breast feeding help!

Paige

So I am 38 weeks pregnant and very patiently waiting on the arrival of my baby girl. This is our first baby and I have zero experience with breast feeding (my mom didn’t do it with my siblings or me). So, what are some must haves? What should I buy extra to go with my breast pump. I have the medela pump on style. I got my box yesterday and I’m afraid I’m going to need to bug so much more. Help.
