Ds1 is 9 in March - he's quite, no, very, sensible. He's been off school this week with an awful cough and I've been leaving him in the house on his own while I take ds2 to nursery and pick him up. I'm only out of the house for 10 minutes each time. I've only ever left him alone before when I've gone to the post-box (which is literaly just across the road - if he looks out of the living room window he can see it).
I'm quite happy with this (so is he) but I don't think I would leave him for any longer. That's illogical really because a disaster could occur in 10 minutes just as easily as three hours. Am I being over-cautious? I have got serious cabin fever after three days in the house and I'm going to keep him off the rest of the week too - but I still wouldn't leave him while I took ds2 to the park, or went to the shops etc. So...what age?
