nursing pillows
Nursing pillows are helpful in the first few months when the baby is a little blob that needs a lot of physical support. It will help you from hurting your back, neck and arms. Also, pro tip: think of the pillow cover like your own bed sheets in terms of cleaning frequency, so whatever model you go with, buy two covers so you always have a clean one.
My brest friend
The Brest Friend has the worst name and is so ugly but it really works and fits well. You end up using that little pocket, the fitted waist band is helpful, and it's almost like a stand up desk for nursing. My husband called it my “stand-up desk for nursing.”
