Here's why:
* Height and Weight: Booster seats elevate children so that the adult seatbelt fits them properly across their hips and shoulders. Most 8-year-olds are still too small to use an adult seatbelt safely without a booster.
* State Laws: Most states have laws requiring children to use a booster seat until they reach a certain height or weight, usually between 4'9" and 57 lbs.
It's crucial to follow your state's specific laws and your car seat manufacturer's instructions.
Remember:
* Even if your child meets the height and weight requirements for a booster, they may still need one if they haven't developed enough to fit safely in an adult seatbelt.
* It's best to consult a certified car seat technician for personalized advice. They can assess your child's size and help you choose the right car seat for their age and development.
Please note: It's important to choose a booster seat that is compatible with your car and is properly installed.
