A five-point harness spreads crash forces across the strongest parts of the body, so keeping a child in one longer is worth doing. Enter your child’s size and your seat’s limits to see how much harness time you have left.
When Is Your Child Ready for a Forward-Facing Harness? Check It
Switching to a forward-facing harness too soon is one of the most common — and most dangerous — car seat errors parents make.
Enter your child’s age, weight, and height. The checker applies NHTSA FMVSS 213 and AAP guidelines to confirm whether forward-facing is legal and safe for your child.
Rear-facing seats absorb crash forces along the full back, head, and neck. Moving forward-facing before the thresholds are met significantly increases injury risk in frontal crashes.
