They don't have as high a profile as the Wars of the Roses or the Crusades, but the Mommy Wars are about as senseless, though admittedly less lethal.
And what are the Mommy Wars? In short, they are sometimes direct, but often passive aggressive battles and skirmishes between women over who has the right way to give birth, feed a baby and raise a child. And since they are fights primarily between mama bears, things can get ugly. However all women can feel free to take part - mothers, mothers of mothers, mothers-to-be. The only eligibility for enrollment is that you're female and that you have something nasty to say about another woman's chosen approach to parenting.
