I think that this is a fantastic step in the right direction, and a positive thing for improving equality for women.
Hopefully over time, this will reduce discrimination against women of childbearing age in the workplace - I know it's illegal already, but there are employers who are reluctant to employ or promote women in case they get pregnant and take a year off.
It's good for families, especially ones where women are the main earner, because now they'll have much more flexibility and choice over how much time each parent wants to, or can afford to, take off with the baby.
I know that not all families will be in a position to benefit - I'm assuming that this option will only be open to families where both parents are eligible for statutory maternity and paternity leave - but it's still a positive step forward.
And I don't agree that this move will now put women under pressure to return to work after 2 weeks. Compulsory maternity leave is already 2 weeks, so employers who are keen on a women returning to work ASAP after birth are already in a position to put pressure on women. I don't see how these new proposals would make that more likely.
I also agree that more needs to be done with regard to affordable childcare to really give parents more choice over work-life balance once parental leave has run out.
