GP has asked sensible 15yr old DD to house sit for 3 days/2 night over the summer. She's extremely responsible and sensible and if she were 16 I'd be inclined to say yes but she's 15 and while the law does not say an age when you can leave a child on their own - the NSPCC says children under 16 should not be left alone overnight.
I'm thinking she shouldn't - GP lives 30 minute drive away so it's not like we can just pop in a few times a day to check on her but we can call/facetime. DH and GP think I'm being overly cautious.
What does MN think?
