DD is nearly 9. Lately she has been asking to stay home sometimes when we are heading out as a family so she can read or draw. I'm not comfortable with that but I do feel sort of, but not entirely, comfortable with the idea of leaving her in an on-site cafe e.g. National Trust cafe while the rest of the family walks around one of the trails.
She could have either my or DH's phone - she wouldn't take the piss and would only use it if there was some sort of emergency. I don't think she is quite old enough yet but I was wondering what age people would think it was ok to do this?
