A Denver woman was pulled over by police for violating state seat belt laws. She had secured a gas can into the car seat, leaving her diapered son sitting next to it without a seat belt.
This is also why car seats for children were invented. Luckily no one was killed. The driver and the child were treated for minor injuries and bruising.
The American Academy of Pediatrics (AAP) says we should keep our tots in rear-facing car seats until age 2.
