Understand this will vary massively depending on the child, but what age would you let your child go to the park by themself.
We live one house down from a play park and football field, in the countryside. Park not ever very busy, more often than not we’re there by ourselves.
I can’t see the park from the house however so it got me thinking what age my children would likely be before I let them go alone. They’re generally quite sensible quiet kids who would just happily play. I won’t say how old yet as would just like to gage a rough age on what others think is generally acceptable.
