As I understand it, though, in the countries where it has been tried, giving men parental leave hasn't made as much difference in the equality stakes as was hoped when it was brought in (read a book about it when I was first going on mat leave - but could be out of date by now).
Exactly how leaveable a breastfed baby is at 6 months varies dramatically. For me, and for many women, introducing formula during the day or trying to express or cut the baby down to morning and evening feeds would have undoubtedly meant the end of BF, which I would not have wanted.
What about lone parents? Wouldn't they just end up with maternity pay cut to four months and leave to six? Hardly fair.
I do loathe the "men are hopeless I couldn't leave him in charge of baby" attitude, though I do think that stems from the fact that if a man takes two weeks' pat leave, by the time the baby is six weeks old, the woman is more than twice as experienced at childcare and this can set the tone for her to be "senior partner," even if she then returns to full time work pretty quickly.
