Breastfeeding

Eileen
So this is my 3rd child my last one was 6 years ago. I am trying to breastfeed for the first time and everything was going good until the nurse at the hospital gave my son some bottles while I was having surgery to get my tubes done. And now he keeps wanting one and I feel like he's not getting enough milk from me cause he'll drink 2-3 oz from the bottles and I pump and only get 1 oz and when I'm trying to breastfeed my son and he starts to cry and push away after a few mins and my husband pushes me to give my son a bottle the stress is just starting to get to me and I'm starting to think about just giving up on breastfeeding cause I don't even think I'm doing it right
