After picking up my 3.5 yo DD from Daycare/ Preschool, I buckled her into her carseat and tightened the straps. She was angry because she didn't want to go home, etc. I turned back to check on her as when we came to a stop at a light down the road and she had completely loosened the straps.
DH and I are big into natural and logical consequences. We are stumped, obviously the natural consequence on unbuckling or loosening her belts is injury or death - not really practical. DH and I are struggling to figure out the logical consequence that will work.
She was able to say (after the fact) that she knew better. And she did it anyway.
We are open to any thoughts or suggestions.
