Right around the time he turned 7, Jameson Mannix started dreading the ride to school. That was the age he realized he was the only boy in his class still using a booster seat. When he complained, his mother, Rebekah Mannix, MD, MPH, of Boston Children’s Division of Emergency Medicine, explained that without a booster seat the seat belt wouldn’t fit him correctly because his seat belt rested on his throat and stomach instead of lying across his hips and chest. In the event of a crash, she told him, the belt could damage his intestines and spine, which is very dangerous.
But Jameson, like most kids his age, was far more concerned with “fitting in” than a well-fitting seatbelt.

That resonated with him a little, but he still fought it almost every morning.”
To help drive home the point, Mannix began researching data on the effectiveness of booster seats and booster seat laws on deaths and injuries related to car accidents, in hopes of strengthening her case for Jameson that booster seat laws for children his age existed for a reason. As she scanned the available data she found plenty of studies linking booster seats to decreased fatalities and injuries, but noticed that laws stating how old or tall children needed to be before they could legally travel without a booster changed from state to state. …
