I nursed for 1 year, ate healthy, exercised regularly, and could not loose weight. When I stopped nursing I fought with my weight for the past 4 years, but it just wouldn't go down or stay down. Now that my daughter is 4 I am finally able to loose weight and keep it off, but it has taken a lot of work! Before I had her I could loose weight so easily and quickly and keep it off without doing much. I feel like I live in a completely different body now! I am down to my pre-preggo weight, in excellent shape, but it sure doesn't look the same (and not as good).
My point: Your body will do what it does and the only thing you can do while you are nursing is treat it well, eat healthy, exercise, and hope that you are one of those lucky women who drops the pounds. If not, you will have to put the extra work in. Good luck!
