I totally agree about encouraging flexible employment practices, Mishap.
The nurseries my grandaughters went to were excellent, but the one my grandson went to in Spain was dreadful (twelve babies with one teacher) and was quickly replaced by his Spanish grandmother.
I think it is all about good childcare, whatever form it takes. I had friends who were miserable and depressed at home with small children and their children would, in my opinion, have been better off in a good nursery. Some were much happier when their children were older, some loved the baby stage and couldn't let go of their children later on.
I think you have to look at what comes out the other end of childcare, not get fixated on an absolute right and wrong way of doing things.
