In Switzerland kids are encouraged to be independant, healthy and practical at an early age but not formally educated until 7.
So kindergarten is until 7 and obligatory from 4. Kids don't undertake reading and writing, but learn other skills which prepare them for the start of school, and life in general. They build fires in the forest, go on mountain hikes, take trams around the city usually with one teacher and up to 18 kids.
It is frowned upon to walk your 4 yr old to kindy. There is one 500-1000m in every village and town and they are encouraged (and taught by the police) to do this alone or in groups of friends.
Most Swiss kids play out all weekend and evening.
School hours are 8-12am three days a week and for two days they return at 2-4pm. They do have homework on the other days, however they also have more time spent on sports and art than I remember my ds doing in the UK.
So three years later to school, half the time spent on sports, 24 hours of education a week total - and are they any less educationally competent than ours? Not really. However all the practical things have fallen into place, dressing, toilet, basic cooking, sharing, helping, exercise, safety etc
Overall the late education keeps kids young, as does the encouragement to play outside, engage in natural activities. You don't see so many Ben 10, Hannah Montanah, Transformer logo'd kids as I remember in the UK. They just don't seem to live indoors or be that dictated by TV etc.
I had a meeting with a sales manager from Mattel once, and she told me that UK girls have generally grown out of Barbie by the age of 7 (starting at 4) whereas this was the opening age for Barbie in Germany. I didn't have kids at the time but it made me feel a bit sad. i had enjoyed Sindy until 11 yrs old, and I wasby no means babyish or mollycoddled.
