Welcome, Keri!
Congratulations on getting the weight off NOW! My baby is 10 years old, and I'm still trying to get the weight off.
It sounds as though you may need to eat more during the day. I don't mean you should chow down, but try having three meals a day with three snacks. Often when we get cravings, it's because we're genuinely hungry without realizing it. We need to fuel our body throughout the day.
Try having a mid-morning snack, a mid-afternoon snack, and another mid-evening.
Enjoy the breast feeding... I loved nursing my babies... it's such a special time.
