I am also breastfeeeding and I do not log my bf-calories at all. I keep them as a surprise for weight-in. Like, say, I should have lost 1lb according to the equation, but in real I lost 3lb. No one is really sure how much milk they produce in one day, it's estimated 300-500kcal so I don't want to log 500kcal and have feeling i can eat more, when in fact i could have made only 300kcal.

Currently LCHF and loving it!
It is foolish to keep doing the same things and expect different results.
