Need to go somewhere between 10.30am and 2pm (approx). Destination is 10 mins drive away. DS 11.5 years old. I know there is no legal age and it is more about a judgement of when child is capable. He is really sensible. I'd pre-make a sandwich and drink and leave in fridge so he doesn't need to use anything dangerous in the kitchen. He will likely just game with friends when I'm out. Thoughts on doing this? (He doesn't have a mobile phone)
