Nursing and pumping issue

My baby is a little over 2 weeks and breast feeding started out rough but is going strong now. I’ve tried pumping to build up a milk stash for evening feeds for dad and for a girls night so dad can feed while I’m gone. I was pumping about 2 hours after nursing with 1-2 hours before baby nursed again. It didn’t seem like he was getting enough: feedings we’re taking twice as long and he never seemed satisfied. so I’ve stopped pumping through the day- just once in the morning and once in the evening while dad feeds him. Does anyone have any insight?
