Ah, but you're missing my point, quattro, and not for the first time
I'm long enough in the tooth to notice that individual lives are just that ... individual. You are in a situation which necessitates full time work and nursery/nanny/au pair provision.
I'm talking geo-politically. I generally do, because if I had to take into account every single individual on the globe before I posted, well ... I wouldn't post at all.
In my opinion, when a society evolves or devolves to a point here it it entirely necessary and expected that both parents must work in order to feel valued/have a roof over their heads, etc., then society must take a good look at itself.
Single parents, like yourself, are a different issue. There are two ways to go: take the state money, or go it alone. I applaud your ethic and your grit, but the OP was about two-parent families, and that is what I was responding to.
For the record, and not for the first time, I am a SAHM who works 35 hours a week. I can do this because I have a partner. Without a partner, I would be on benefits, because I don't have a career which would pay enough to pay for nursery fees.
