Would you give an 8 yr old a choice between a harness and a booster? Until she was 7 there wasn't much of a choice because she would slump when she fell asleep. For the past year I have given her a choice every so often and she typically chooses to stay in a harness. Should I tell her too bad and make her ride in a booster now? She doesn't fall asleep in the car nearly as much and when she does she can stay in position.
