I’m 9 Years Old – Do I Really Still Need a Booster Seat?

My son doesn’t want to use a booster seat anymore. I can see his perspective: none of his friends use one any longer and he thinks the seat belts in our cars fit him just fine. So why bother?? Because he’s just nine. And because crash studies and child safety guidelines from experts like the American Academy of Pediatrics indicate that  he still needs to be using one. Although he thinks he’s so smart and grown up, he’s just a kid – and I’m the parent. And I actually know what it feels like to be injured in a car crash.

Guidelines issued by the American Academy of Pediatrics in 2011 recommend that kids use a booster seat until they are at least 4’9” tall (57 inches) and weigh between 80 and 100 pounds. This will likely be around the ages of 8-12 years. But it’s the physical dimensions that matter most. Kids need to be large enough to fit properly in the seatbelt – and mature enough to ride without slouching down and defeating the whole purpose of the belts. Focusing on the age of the child to guide booster seat decisions can be misleading. Last spring – at 9-years of age – my son measured in the 75th percentile for both weight and height at his annual pediatric visit (meaning he was taller and heavier than 75% of other nine-year olds)….and he STILL DIDN’T meet the criteria for graduating from a booster seat – he’s not yet 4’9” and weighs only just over 80 lbs. So why are we in the minority in our community in still using a booster seat?

The problem is that many state laws – and therefore local communications about what constitutes safe car travel for older kids – haven’t caught up to these recommendations (click here for a summary of state laws on child passenger safety). Many states – like Alabama, Colorado, Iowa and Nebraska (to name just a few) focus exclusively on age – without the all-important height and weight requirements. This list includes my state of Indiana which allows children over age seven to shelve the booster seat, no matter how big they are. My son’s best friend – also nine – stopped using a booster seat last year. He’s fully THREE INCHES shorter than my son. How can he possibly be safely restrained by an adult seat belt during a crash? And this isn’t just a theoretical issue. Safe Kids USA reports that children seated in a booster seat in the rear of the car are 45% less likely to be injured in a crash as compared to those using a seat belt alone.

While this is bad enough, some states – like Florida, Arizona and South Dakota don’t even have booster seat laws. In these states it is legally permissible for children as young as age 4 and 5 to use adult seat belts. Is there some reason why the children in these states are less likely to be involved in a traffic accident – or that they are somehow more resilient in a car crash?

Let’s face it – the process of proposing and passing laws is complicated and time-consuming. Hopefully all these states will eventually get on par with the guidelines, joining states like Georgia and Maine. However, in the meantime it’s our children riding in the back seat and I would rather base my car safety approach on best-practice guidelines than rely on the timeline and politics of my state judicial process.

So, in our house the 4’9” rule prevails. We even got out the measuring tape recently and determined my son has an inch to go. He’s counting down every day. And he understands that I’m following new expert recommendations to keep him safe – and that his friends’ parents probably just aren’t aware of these guidelines, which is too bad.
