Pumping!!

mo

How can I bring back my supply before I dry up fully? I’m so upset I stopped pumping about 3 weeks ago... I felt like my milk wasn’t filling him up and I was so tired. I now have so much more energy and want to start pumping again because I know it’s the best thing for him. When I do pump it’s only a few drops 😭 Can I get back to how I was, making about 8oz at a time (4/5oz each breast)?! Need some tips!
