I'm asking because it's stormy weather outside and DD said she didn't want to go to the shop, my first thought was "okay, I'll be back in a second" just because she seems so mature, but I'm not going to do that... I feel sure that she is too young for this yet so I will drag her out with me in a minute. The shop is a Sainsburys literally directly opposite us, I can look out the window and see the offers on shelf (Chocolate Leibniz for £1... I can see this from my living room window that's how close we are). Sometimes when she is asleep at night and I realise I need something I find it frustrating that I'm looking right inside the shop yet am anchored into my house. I'm single, so no OH to stay in while I pop out, I have a friend over if I need to go out at all in the evenings or ask a mate to bring bits.
So when would be an appropriate age for a child to be left alone while mum pops into the shop across the road? I'm guessing like 8/9/10? What do you think?
