Breast Feeding Advice Needed!

I didn’t breast feed with my first. I’m due with my second in July and plan on breast feeding this time around.

My main question is what is the best wearable pump or just the best pump in general, price and comfort-wise? Preferably something that can be ordered off Amazon.

Also, are there any essential things needed for breast feeding that I might not think of? Please any advice helps since I have no idea what I’m doing!

I didn’t breast feed with my first because I had trouble with milk production and had a bad experience with my lactation nurse so I ultimately decided to formula feed because of it.
