A wonderful tip for handling siblings who fight in the back of the car from the In a Strange Land blog.
“Before you start the car trip, buy a packet of chocolate frogs.
As you all get into the car, children in the back seat, adults in the front, the adult(s) should open the packet of chocolate frogs. The packet of chocolate frogs should be left in full view of the children.
Then, start driving.
Sooner or later, the bickering, the shoving, the kerfuffle, the noise, the complaints from the back seat will get to be too much for the grown-ups to bear.
At that stage, the adult(s) should reach for a chocolate frog. They should wind the window down, and throw the frog out.
At the end of the journey, the children may eat any frogs that are left.”
Like any reward/punishment strategy, it may not address the underlying behavior and may not make the kids genuinely want to stop fighting. However, I can’t help but feel it would be a lot of fun to try. We have a three hour trip to the beach this week so I will keep you posted!
