What should be done if a child can pinch the harness straps at their shoulders?

When a child can pinch the harness straps at their shoulders, it indicates that the harness is not snug enough. A proper harness fit should prevent any pinching; if the straps can be pinched, it means they are too loose. Tightening the harness straps ensures that the child is secure, providing the necessary restraint in the event of a crash. A snug harness helps to reduce the risk of injury by preventing the child from moving excessively within the car seat.

Maintaining the correct fit is crucial for safety, as it keeps the child properly positioned in the seat and reduces the likelihood of ejection or excessive movement during a collision. Ensuring that the harness is appropriately adjusted promotes effective protection for the child, making this the best course of action.
