For nursing mothers, its very typical to have most the baby fat just fall off, but then have trouble losing the last 10 lbs. That is the typical standard, but of course 13-14lbs isn't that far off. I know with my children, I gained alot (50-60 lbs) during my pregnancies. I nursed both of them and lost the majority of my weight within 3 months. With my first, that usual 10 lbs did stay on me until I weaned him. After that I had no trouble losing it. I am still nursing my second, and am in the same boat as you, with a little under 15 lbs to lose. I wouldn't worry too much about it. Once you wean it will be much easier to lose the weight because you're appetite will decrease. It is your body's way of ensuring that you have enough energy to supply yourself and baby with food, and it is the norm for your body to want a little more fat when you're nursing, which it gets by increasing your appetite.
