I do have an opinion, Harpsi.
I think there are some excellent nurseries out there (Bubble's for instance - clearly, she has the children's best interests at heart).
There are some diabolical ones as well, where low-paid, high turnover teenage staff smoke while pushing the buggies of their charges down the high street (seen it with my own eyes).
So to make sweeping statements about childcare will always get the parents from the former sort of nursery going, "But MY nursery's excellent, how dare you say this sort of thing?!" and parents from the latter nursery either don't care enough or feel too guilty to post - if they're on MN at all
I live near enough willing and able family, so I am very lucky with my childcare. But, ironically, if we didn't live where we do, I'd probably be able to afford to stay at home. But, on balance, I prefer the children having their GPs near them - and if I was to take DS2, in particular, away from MIL, they'd BOTH sob for a year. He prefers her to me
