I have one side that produces much more and I wake up with painful engorgement in that side once a night. The most I go without feeding during the night is 3.5 hours. I need to either pump or hand express to relieve the pain. I was hoping engorgement would go away by now. LO is 5 weeks and I am feeding on demand. The breast does feel empty after he finishes and we still have very long feedings (most over an hour, occasional 2 hour nighttime feedings). Any suggestions?
