Also, how do they stay so fat nursing babies?  I wonder that as well.  Every ounce of my pregnancy weight dropped off within 6 months just from breastfeeding.  I didn't have to restrict or count a single calorie.  The baby weight just melted off (as it should!). Bonus tidbit: My gyno told his patients that, if didn't intend to breastfeed, you should gain 10 lbs LESS than the recommended weight during pregnancy.  So if you were a healthy-weight shitlady before pregnancy with no intention of breastfeeding, you shouldn't gain anymore than 25 lbs during pregnancy; if you did intend to nurse, then 35 lbs.    If you were overweight to begin with, you should gain even less weight.
