I want to stop pumping

My baby was born with low blood sugar so he was bottle fed from the moment he was born. I tried nursing in the hospital, but i was so out of it from the c section the first day and didn’t get off to a good start. He gets frustrated and i could never get him to actually latch.

Once we were home, I decided to exclusively pump. It takes so long and I barely get anything. I just think I want to be done...I barely get an ounce or two each pumping session and he wants to eat constantly. He’s 3 weeks. I’ve only pumped 1 or 2 times for the past few days. Can i just stop?
