What about the new law about seat belts.
7 year olds would never sit in a booster seat. There at school and like to think of themselves as big kids. I know that when I started school I no longer wanted to have to sit in a booster seat. This was OK. My parents felt it was safe for me and all my brothers as long as we kept our seat belts on.

Some parents may choose to let their kids sit in the booster seat till their 7 years old, but on the other hand others might choose to trust their child to sit on the seat with their seat belts on. Again it should be up to the parent since it is their child they should have a say in this.....
