Exclusive Pumpers

tnshall

Hi all! I'm a lurker but needing some advice. For various reasons due to lack of good consistent weight gain I have decided to begin exclusively pumping. My DS is 3 months old. I have a well established milk supply. I can pump 5-6oz during one session and he only takes about 3-4oz. My question is can I go longer between pumping sessions and maybe get a little more without tanking my supply? I currently am pumping every 3hrs(when he normally needs to eat) but would like to spend a little less time with my pump. If I could somehow go 4-5hrs and get about 8oz that would be great. Any advice would be appreciated. Thanks!
