One of the many reasons we moved our young children from the UK to Scandinavia was to improve their childhood by reducing hazards & risks whilst also being in an environment that was more acceptable of those risks. (The paper distinguishes risks vs hazards as something the child can perceive & control vs something they can't, like a car or unsafe equipment).

My children had whittling knives from age 5, built their own fires when we went on walks, could explore into the small woodlands on their own soon after and walked home from school at age 7. None of this would have been socially acceptable in a UK city but was pretty much standard in Oslo. Our children still feel safe and also feel confident doing things themselves. Our level of stress about our children seems to be lower than my friends elsewhere, who have a risk avoidance mindset, living in a society that highlights any potential risk as to be totally avoided and bad parenting if a child is exposed to any risk.

Occasionally you hear stories from the US about parents being arrested for letting their children walk down the street alone or play in the local park by themselves and that seems crazy to most of the rest of the world.
