I think one of the problems with this is that women tend to be made to feel guilty if we return to work and don't look after our children ('What's the point in having children if you don't see them or look after them?') but also made to feel guilty if we don't work because we have children (i.e. what you're doing now).
I don't think what you're doing is wrong in itself, I just think that we need to get rid of the culture of stigmatising both options, because what are women supposed to do then?
I do think that the help with childcare is great! I know several women (through working in a nursery) that started work and put their kids in the nursery and then had to quit work because the childcare was costing them more than the wages they were getting (although I can tell you right now that money wasn't going to us, we get minimum wage).
I don't think this woman has much right to complain. They're not cutting child benefit in total, they're cutting it for those that don't need it. It's not like they're taking the child benefit away from poor non-working parents to give it to poor working parents, they're helping both... If her child benefit has been cut then her husband (I assume) must earn a lot of money, so she doesn't need the child benefit.
I do think a better thing would be to make it so that nurseries can't charge more than a certain amount per place, as I see them putting their prices up now so they can take the vouchers and some more to make extra profit. But also keep in place the number of staff per child rules; I know some nurseries wanted to move the 1:3 for the under 3 year olds up to 1:4 or even 1:5 and that is just dangerous (not to mention extremely tiring. Looking after 3 under 3 year olds on your own is bloody hard enough!). Nurseries make an awful lot of profit, my old boss and her sister and her husband and her sister's husband (who all own the nursery together) go on like 5 foreign holidays a year and have all had plastic surgery and stuff like that while we get minimum wage!
