Exposition - Should 7 year old have to sit in a booster seat?

I believe 7 year olds should not have to sit in a booster seat.

Firstly, they're big enough. Secondly, it's not good for their confidence. Finally, they are old enough and don't have to sit in a booster seat.

Children of 7 years of age should not have to sit in a booster seat because they are big enough.
