To jump on my soapbox for a minute, we as a society need to recognise that times have changed.
Once upon a time, most households survived on a single income, with one partner (normally the mother) staying at home to do the necessary work there and raise the children.
This is fundamentally no longer the case.
Now both partners have to work, perhaps multiple jobs.
The grandparents still have to work.
The parents may have had to move away to find that work.
Full time child care should be free for tax payers.
Yes that will be expensive.
Yes people will rort it.
I don't care.
It pays a societal benefit to have educated, well fed, healthy children.
Even the poorest ones.
Perhaps especially the poorest ones.
