At first the mother (an NHS nurse?) changed her job to night shift and then had ti get up to drive the girl but that was not going to work longer term I think the Telegraph said.
Anyway Labour can change the law even if it means no benefit to the state of course - Governments often change laws in ways that cost everyone more money but they decide morally that is what they want to do so I certainly do not think labour has to justify every police simply on money grounds; but I don't think the law change is legal and I hope the litigation is won against the state in April.
If we are all in this together why not give every parent child benefit which used to be the case when I had my 5 children until the law changed and it was withdrawn from higher earners. If people don't also take out of a system then they don't support it and that does not always benefit the state. If we all pay in and take out eg everyone gets the 30 fre ehours from 9 months, just just the less well off, then it is more of a universal system and the 10% of people on £4200 a month after tax that puts them into the top 10% who pay the highest tax burden in 70 years might be happy to work hard and pay tax rather than work less.
