Breast-feeding helps you shed post-baby pounds?

I've heard many'a different things about this. Some women swear by it, others say it doesn't do anything and it's just an old wives tale.

For each of my kids, while I breastfed, I lost weight.

Thanks. Usually, I'd be allowed to lose 2-3lbs a week but apparently if breast feeding it's only supposed to be 2.5lbs a month!

I guess I'll invest in a good jogging stroller. Definitely walk/jog everyday to help me out.
