Yah with both my kids I can pump more then 8 oz every 3 hours but I wanted to feed him first before I pumped. and I do love to sleep lol so I just wait to wake up so I can feed him. even tho My breast r so full by the time the time he wakes up lol
if he keeps up sleeping through the night and you have no reason to pump your body will adjust. Sadie sleeps from 9-10 til 5-6 and I don't pump and I'm no longer uncomfortable in case your like me and would rather sleep than have to pump plus my daughter doesn't take a bottle
