Can anybody confirm that studies now exist that refute the "baby-rejects-breast-after-exercise" study, attributing the refusal to lactic acid in the mom's milk? I know I saw somewhere that new studies disagree with the original studies, and that this lactic acid effect is minimal or nonexistent... Personally, my two daughters have never complained, even though I'm an avid runner, and though my eldest was old enough to verbalize her complaints at age 2 1/2, she never did. Considering the fact that she complains about everything else, I'm sure if she'd noticed a difference in my milk she would have protested.
