13 yo DS at home alone overnight

[TeenNegotiator]

I have to go away for work for one night in a couple of weeks. I spoke to DS about it earlier and I said I would ask his maternal grandma to pick him up to stay at her house or I could ask her to come and stay here. My sister and brother in law live next door but one too so he could also stay there.

He asked to stay at home by himself. My initial reaction is no, but I'm curious, what age would you allow your 13 year old to stay at home by themselves?

My mum lives 10 minutes away, my other half lives 10 minutes away and like I say, my sister and brother in law live next door but one. So we have plenty of people around us. It's the fact that my sister lives practically next door that makes me wonder if it's ok.

He's very mature for his age and I'm happy for him to be at home by himself it's just the overnight bit that is making me nervous.

What would you do?

too young. He says he will be fine but he is a child and therefore unaware of all the things that could go wrong - he has no life experience to deal with emergencies or just if he got scared alone and didnt sleep well. Plus there is family next door etc - so no reason for him to be sleeping overnight on his own. Plus it isnt even just the dangers of the home or people (eg a breakin) but also onine dangers and no supervision around for a long period. I personally would not do it - not when he could go to family nearby or have them come to him.
