I don't usually, but I have a casserole in the oven, and I need to go out. Ds has to go to karate, but the other boy who goes with him is ill, so I have to take ds (supposed to be other parents' turn).
My cooker is very new (january) and has a timer that turns the oven off. I will be gone for an hour and a half at the most. If I turned it off while we were out, it would take to long by the time we got back.
Verdict please!
