Which statement by a parent indicates further teaching is needed regarding car seat safety?

The statement indicating that further teaching is needed regarding car seat safety is the one about adding padding behind the child's back. While comfort for the child is essential, adding extra padding can compromise the effectiveness of the car seat's safety features. Car seats are designed for specific dimensions, and any additional padding can interfere with the harness system, preventing it from fitting correctly and reducing its ability to protect the child in the event of an accident.

Proper car seat safety protocols emphasize that harnesses should be snug against the child's body without additional padding that is not approved by the manufacturer. It is crucial for parents to understand that the purpose of the car seat is to secure the child effectively, and any additional items that alter the car seat's designed fit can pose a risk.

In contrast, positioning the car seat at a 45-degree angle is typical guidance for infants to ensure their airways remain open. The mention of covering the straps with a blanket could suggest a misunderstanding about strapping safety, but it may not immediately require teaching since it's acknowledged that the blanket should not be underneath the harness. Lastly, placing the chest clip at armpit level aligns with best practices for proper harness placement, ensuring safety in the car seat.
