Breastfeeding

Hello,
I was just wondering..after getting a few diff opinions such as my mother in law who says you don't lose any weight and possibily gain more weight while breastfeeding, and my sister who says you lose weight and get your uterus back to reg size...what has your experience been?

i haven't lost or gained

I lost weight.

lol, it doesn't make you gain weight. it tightens everything up though. a health nurse just came here and said breastfeed as long as you can. ideally until your child in 2 yrs.
