Kristin Cavallari and her son Camden are beautiful.
But everyone is curious how Kristin lost her baby weight so fast!
"The biggest thing was i didn't gain more than I was supposed to during my pregnancy. Plus breastfeeding was 500 calories a day."
Is there a nutrition label on the back of the baby that tells you that?
That's not fair that only women with babies can lose weight like that.
