I sometimes think that some people are short sighted, when it comes to long term and societal consequences of encouraging certain behaviour .
I understand the whole " it takes a village " mentality, but it seems we have taken this saying and distorted it.
Where it once meant that people actually were involved in other people's lives, relatives, neighbours, people in the community, physically showing up and helping bring up our children, has now seemingly become, at least on mumsnet, a case of people informing authorities when a parent "parents" in a different way.
Your post centres "playing out". It doesn't lead with violence or abuse or any other particularly worrying issue that would make someone take notice about a child's welfare. You say that there are other issues. Well if the other issues warrant intervention, lead with those.
Playing out relatively young can also be a parenting choice. I'm not saying it's always decided upon with thought, but it often is. I way up what I think is beneficial to my child in the short and long term, look at the statistics, and make my rules.
It's funny how we tend to be so worried about types of behaviour that lower working class families, or families that live in rural communities adopt. Parents send their children to forest schools, but wouldn't let their kids play out and build dens in a wood. Parents in towns and cities are so keen on getting swimming lessons, but god forbid a child sets foot in a river or a lake to swim. Or is it for if they fall into a canal while drunk at University.
People don't tend to worry about the risk to young elite gymnasts or ballet dancers that are training away their childhood, or much worse, at 8 years old. We don't call social services on their parents for putting their children at risk of abuse or developing eating orders later in life. The chance of becoming "someone" is somehow deemed worth it.
When children are hot housed into high performing schools and then struggle, we probably think poor kids, but we won't be informing anyone.
Somehow it's things like "my child's friends has stained clothes and I know for a fact she hasn't had her hair washed in 4 days! " that make people immediately think they are saving a life.
