Turning a child from a rear-facing restraint to a forward-facing restraint too soon. American Academy of Pediatrics (AAP) now recommends keeping children rear-facing until 2 years old if possible.
Restraint is not secured tight enough — it should not shift more than one inch side-to-side or out from the seat.
Harness on the child is not tight enough — if you can pinch harness material, it’s too loose.
Retainer clip is up too high or too low — should be at the child’s armpit level.
The child is in the wrong restraint — don’t rush your child into a seat belt.
