Maternity leave is not about breastfeeding, it's about the parent spending the majority of the first year of life with their child(ren).
It's perfectly possible to work from early on and breastfeed - I have several friends who did this, all you need is a good pump and some determination. And anyway, it's an equality question, not an infant nutrition question.
The point about women being bullied back to work because dad wants to have time with the baby too, doesn't stack up. At the moment men are forced to work, without the option of looking after their child full time for an extended period of time. Nobody asks the men whether they'd rather work or stay at home. Nobody asks the women either. So without equal rights to parental leave, both men and women are forced into situations they might not have chosen if given the choice.
In Germany paid parental leave is 12 months if only taken by one parent, but if shared can be extended to 14 month. Women have to take off 8 weeks after birth, but what is done with the rest of it is up to the couple. It's also possible that they take the leave simultaneously, i.e. the father takes the first 2 months off after the birth, and the mother stays at home for a full year (or he stays off a full year and she returns to work after 2 months), and it can also be split 6/8, 7/7 etc, whatever they decide.
I don't see how this government's leave proposal makes anything more difficult for small businesses, as it doesn't matter whether they have recruit cover for a woman or a man going on parental leave, unless they'd admit to not employing women of childbearing age to avoid this "problem".
I think there;s still a long way to go towards equality, but this is a first step, and a positive change for men and women, who don't want to be stereotyped into gender roles.
