Suddenly only nursing from one breast..

Jessica

My son has suddenly decided he will only eat off one breast at a time. He will eat off either breast I give him, but not both during one nursing session. He went from about ten min off each breast one day to about ten min off only one per feeding the next. I believe it started because of having thrush, but now we’re going on two weeks of this and I’m going crazy. He is still being treated for thrush, but doesn’t seem painful. At first I wasn’t pumping the opposite breast thinking his nursing would go back to normal, but since it hasn’t ive started pumping 1.5-2 oz off the breast he doesn’t eat from because I’m afraid of losing my supply. He doesn’t act hungry. He isn’t fussy. He doesn’t seem to be losing weight although I don’t have a way to weigh him at home. I don’t know what to do. I called a lactation consultant and they weren’t much help. I’m sick of pumping every time I feed him. Any advice? He will be 8 weeks old tomorrow.
