breast feeding is going down hill

anna

I'm struggling. My baby has been nursing and for a few days seemed to be doing good, now it seems like she isn't getting enough may be. She will eat and be fussy, so yesterday I gave her 2 oz breastmilk in a bottle after she cried for over an hour fussy and she got ok. Thus morning she just nursed and than was fussy and I gave her more milk in a bottle and she calmed down. I've been pumping after she eats and storing the rest (around 1 oz) in the fridge I haven't been pumping much extra. But I'm wondering now if I should stop pumping and just soley nurse, as maybe I'm drying myself out? She didn't eat for 4 hours during the night and I didnt pump either, and when she woke to eat I was full and she ate enough to get full as well and slept for a few more hours. But I know pumping after they nurse is supposed to help with supply too right? I'm torn not sure what to do.
