I suppose if they have to be in school..

then there's worse places than Sweden (i.e. the UK school system).
Here's a link showing the way Sweden runs it's preschools and how it seems beneficial long-term as regards literacy. I do think though that Swedish is a lot easier to learn to read as it is generally more phonetic. (I'd advise putting mute on until title comes to avoid garish music)
Funny, they have fairly recently built an outside shelter so the little ones can have their nap outside in H's nursery, whatever the weather. The chairs and tables are exactly the same as in his nursery. Only thing they don't show is the kids whimpering for their Mummy (although I admit this isn't a hughly regular thing I come across), nor the whiffy nappy changing area.
I think they have got it right not pressurising the kids to do formal learning until 7, but 'social training' was mentioned ! and I think age 1 is too young to go to nursery, especially when it can be from 7 am until 5 pm, 5 days a week.
