Cameron says so. The government's view of the importance of the family couldn't get any lower.
I can think of little else, except abortion, that demeans mothers and their vocation more than a Government telling them they don't want to 'work hard and get on' by bringing up their own children.
Women are damned if they do and damned if they don't. If they do go out to work and they have children, they are often penalised in the workplace for not being focused enough on the job to do it properly. If they stay at home they are work shy potential scroungers who are after a free ride.
Having stayed at home, there's no denying it can be lonely, frustrating, and boring, especially when everyone else you know with children is out at work after putting their kids in day care. Financially it's not always great either. But there is nothing natural about separating small children/babies from their mothers and herding them together with a dozen or so other small children.
A nursery is not a home, a childminder, however kind, is not a parent.
Mothers who stay at home to look after their children want THEM to get on.
