I have been often judged harshly for not subscribing to parental paranoia and refusing to breach trust with constant surveillance. I stand by my choice: surveillance harms trust, children need space and safety is good enough. I'm way too old to be sensitive to the opinion of other parents !
It's interesting that some parents seem to be more worried about what their peers think about them, than about giving their child the opportunity to grow to be well-adjusted and independent.
And because people are encouraged to look at any sign of child neglect (for some reason), dirty clothes or bruise that could be acquired during play, could be easily misconstrued as child abuse.
