As for weight loss, I am at 122 lbs. 3 lbs away from my goal. I got this from the Moms Into Fitness site:
Breastfeeding and Weight Loss
If you are breastfeeding you need to add 300-500 calories to your daily caloric needs for a singleton baby. This is without exercise. If you are trying to lose weight while breastfeeding the best way to monitor this is weighing yourself every Monday morning and if you aren't losing ½ - 1 ½ pounds/week you may be eating too many calories (or in some cases not enough). At the same time you must make sure you are consuming enough liquids and protein. And make sure you are producing enough milk. You need more protein during breastfeeding than during pregnancy!
Keep in mind your weight can stay steady over the course of several weeks to maintain enough fat needed for breastmilk production. It's safe to lose about a lb. a week while breastfeeding. Although for smaller women or women with a lower Body Mass Index it should be closer to ½-1 lb. a week.
I think I lose a couple ounces a week. I am still breastfeeding and am on birth control (which I think adds to the weight gain), so I'm not worried about hitting my goal weight.
