When my baby was first born, I noticed I could eat anything and still lost weight. But that caught up, and now I am so hungry all of the time, I feel like weening would make me less hungry and maybe I'll lose some! ? thanks!

Breastfeeding burns calories. Anywhere between 300-500 a day. If you stop breastfeeding and continue eating the same,as if making up for calories burned, that can over time attribute to some weight gain.
Just need to eat a bit healthier and watch what you're snacking on throughout the day. Stay away from the junk foods and eat a good breakfast. Don't be temped by donuts or sweet things in the mornings.

When you are feeding your baby, you're still "eating for two". All the baby's calories are going into your mouth and out of your nipples.
When you wean him, you'll need to cut down your own calorie intake. Otherwise you'll gain weight (or at least stop losing weight as quickly).

When I stopped nursing my apetite actually went down and I lost 20 pounds, I weigh less than I did in high school! :) I was the same way when I was nursing too, I was always so hungry.... I guess it's different for everyone though!
Sending good vibes your way.... :)
