When I went back to work, despite trying to nurse Timothy on that side first & third at every feeding, (L-R-L), when I pumped at work, the most I ever got was 3 cc. I had nursed the two girls without difficulty -- the only thing that could account for it was that I had a mastitis with daughter number 2 on the left side -- and milk supply diminished at that time, but not completely. NEver found any reason for lack of mmilk; had a mammogram when I stopped bf and have had several since (Tim is almost 13), but nothing has ever shown up. Virtually the same thing happened to my sister with her third child -- she ended up, as I did, one sided nursing from about 7 months until Rebecca weaned at almost 2. My guess is a variation of normal, but after weaning I'd suggest she have a mammogram just to make sure. Jan Barger
