"So you have 7-year-olds waddling around the city on their own" This. I have seen so many kids going to school alone in Tallinn - quite the opposite of the current generation's helicopter parenting.
As an Estonian currently living in Demark, the contrast is very stark. Kids in Copenhagen don't have any freedom at all. Parents are climbing playground equipment alongside them, touching their playballs every 10 seconds etc. On top of that they are holding protests that this isn't enough.
> aim is to persuade the government to introduce a minimum ratio of 1 adult to 3 children in nurseries (roughly 0-3 year olds), and 1 adult to 6 children in kindergartens (roughly 3-5 year olds)
