I'm trying to sort in my head some of the things my parents did when me and siblings were growing up to see what was normal and was was not.
When my parents used to go into town ie the high street, if they had their shopping to do or something like a bank appointment they would drop us at the toy store and leave us there playing with the toys until they'd finished and then they'd come back. Probably used to leave us for about an hour but I'm not sure if it was longer. We were about 4/5 when they started doing this
I can't imagine doing this. It was early 90's though so I don't know if it was normal or not.
