Losing weight while breastfeeding

I recently quit breastfeeding; see my post on it here

While I was breastfeeding, I was losing 2-3 pounds a week and eating lots.  (Two lunches, seconds at dinner, lots of brownies, etc.)  I’ve figured out why:

This first week after breastfeeding, Caleb is eating 700
calories a day.  Assuming he was consuming 700/day breastfeeding,
that’s 4900 calories/week which is about 1.5 pounds a week and that
doesn’t count production costs!

Am I sorry I quit?  Nope.  I’ll just use all my extra time to get some exercise, which I have really missed.
