I have a 5 month old baby and often worry about the rules on paying for petrol when I have my daughter in the car. Is it safe to leave her asleep in the back of the car with the car locked while I pay ? Or am I expected to take her out of her car seat and carry her across the forecourt. What do most mums on here do? Is it really frowned upon to leave them in the car for a few minutes while I pay for petrol?
