Can anyone give me some advice please. For the last few days DD3, who is 15 weeks, has been fussing at my right breast pulling on and off and getting upset. She only calms down when I swap her to my left side and will happily feed. When I try to sqeeze milk out of right boob there is nothing there, boob feels soft even when left for several hours. Left boob however feels constantly full. I have been trying to put her on right boob more often to stimulate it more but she just gets upset. Have tried expressing tonight but nothing! I am not ready to give up breast feeding but obviously can not go on like this. Has anyone got any ideas why this has suddenly happened and what I can do about it?
