I wasn't allowed to "play out" I had never heard the expression.
I never found out why my parents were so against it, as it was plain to me, even as a child, that they had both been allowed to do so, and neither of them, or their sisters, brothers or cousins had come to any harm.
I was frightfully envious of the children who were not under their mothers' eye all the time and finally at the age of 11 or 12 was allowed to go for walks by myself, even without the dog.
I think it is dreadful not allowing children to stand on their own two feet. Obviously, what we let children do must be suitable to the age, but right now, three year olds cannot even use the toilet on their own.
Frankly, if the fear of sexual abuse is what is riding their parents, you would think the earlier a child learned to use the toilet alone the better, wouldn't you?
