I would always gtt petrol at night when paris was a baby, so that Marc could either do it or watch Paris so I could. Otherwise find some Pay at Pump Petrol stations that way you can just pay with a credit card. Now that she's older its easier to just take her in with me. Personally though I wouldn't risk it. But my philosophy is if you wouldn't leave your bag/phone/wallet in the car then don't leave your kids you can replace your stuff your kids on the other hand
