The town I live in renovated a park to have a gigantic playground, and every nice weekend day I’ve been there there’s tons of kids and parents there. On Halloween there were tons of kids out despite it being around 0F out that night. But random weeknights? I don’t see kids playing in yards much. I don’t see kids riding their bikes to convenience stores to get snacks. I think the risk acceptance of parents has shifted a lot plus kids are more able to occupy themselves with fondleslabs so they have multiple reasons to not go outside
Playgrounds are fenced off and parents constantly stay within 2 steps of their helmet wearing kids here in Czech Republic. When those kids are older than toddler age, they disappear from public life.
It’s not like that in my home country where maybe they just sit around playing with their phones, but at least they’re outside with friends.
