Not at all? For 2 minutes while you pay for the petrol? Or longer?? I have been leaving my sleeping children in the car (not hot day, in the shade, doors locked for no more than 10 minutes) to go to shops I know they would be hell in, for a few minutes or so. I then come back, they are still asleep, (it being their nap time) and we then go home. Is this wrong? I feel bad doing it, but I would feel worse waking them both up during their naps, hauling their grumpy bodies out of the car and bringing them to inappropriate shops (ie a china shop where I had to get a wedding present). Am I a bad parent??
