I had this problem with my first daughter. My 10 day old prefers my left side. She latches better, swallows consistently and is happier on the left side. I often start on the right and then switch over to the side that she likes. I was concerned about her weight and for 2 days I gave her more feedings on the side she likes because I knew she'd eat more that way and she'd also get the hind milk if I stuck to one side for a few feedings. Both sides were full of milk, engorged, leaking.....now today the right side feels soft and empty! What have I done? I tried pumping it and got almost nothing! What a fast change. I want to maintain my supply in that side. It doesn't have to match the output of the other side, but I want to keep it going.
What should I do??? Is it too late? How do I re-build it now?
