When Ashlea was younger I would always take her in with me, but now that she is older she understands the "can you wait in the car while mummy runs in and pays?" and sits there happily, as long as i can see her clearly while inside. I was worried when she was younger that she would freak out and cry being left there by herself.
I always lock the car to pay regardless of wether she is with me or not.
We used to always fill up on the same day, so Wednesday was "petrol and pop (icey pole) day" She's sit there waiting like an angel cause she knew she was getting an icey pole.
Now I dont mind if she wants to come in cause she unclicks hersellf, comes in, and clicks herself back in the car and its all easier than when she was younger.
