I'm having pain in my right breast and the hospital lactation specialist suggested that I give it a rest for a few days and pump that side. The pain is behind the nipple, like a breast tissue pain. I've been treated for yeast but it seems that isn't the problem as neither I or my baby responded to treatment (my son didn't show any signs of thrush). I'm wondering approx how much I can expect my 10.5 week old son to drink. He's 13 1/2 lbs and 24" long. I just started this today and pumped 4 oz on that side earlier but he drank down 6 oz of breastmilk I had frozen. Is that too much or is that expected at his age/weight? He actually seemed like he may have wanted more too but I was afraid to overfill his belly. Any help would be appreciated!!
