Just seen another thread on v v similar lines, but I've just popped to the shop with my 5 year old and left my 7 year old at home playing the computer. (He didn't want to come, and he's been so good all day in the heat, and was happily playing his computer, I didn't want to drag him out).
I've never left him before. We checked what to do in most eventualities before I left (eg. Go out back door if there is a fire, don't answer the door if anyone rings the bell, call mummy if you are worried about anything....)
I was gone approx 10.34 minutes (I was glued to the clock!!) But was worrying for all of those minutes, and now trying to decide if what I did was really really wrong, or fine!
My 7 year old was absolutely fine when I got back. Still sitting at the computer in the same spot, and had barely realised I'd gone!
What do you think? Is 7 too young to be left alone?
