Re: Latch key kids
In your situation, I would say 'yes'
It wouldn't work for all 12yr olds or even some 14yr olds.
The fact that grandad is next door will make him feel secure and will give you peace of mind.
I was much younger when I got a key on string round my neck, and I remember that that key was 4" long. I did have a brother 3yrs older, so I wasn't alone. That was a time when neighbours cared as much as any relative does today, so there always would be help if any emergency arose.
