A nurse is reinforcing teaching about car seat safety with a parent of a newborn. Which of the following statements by the parent indicates an understanding of the teaching?

Keeping a baby rear-facing in the car seat until they reach the age of 2 years old or until they reach the maximum height and weight limits recommended by the car seat manufacturer is a crucial safety guideline. Rear-facing car seats provide better support for a baby's head, neck, and spine in the event of a crash, reducing the risk of severe injuries. "I should place my baby in the car seat at a 90-degree angle." The correct positioning for a rear-facing car seat is typically between a 30 to 45-degree angle. This angle helps ensure the baby's airway remains open and prevents their head from flopping forward. "I should position the car seat's retainer clip at the level of my baby's belly button." The retainer clip of the car seat should be positioned at armpit level, not at the level of the baby's belly button. The retainer clip is designed to secure the harness straps and should be placed across the chest, resting on the bony part of the shoulders. "I should enable the airbag when my baby is in the front seat of the car." It is not safe to have a rear-facing car seat with a baby in the front seat of a vehicle with an active airbag. Airbags can pose a significant risk to infants due to the force with which they deploy. It is recommended to place a rear-facing car seat in the back seat of the vehicle and disable the airbag in the front passenger seat if the baby needs to ride in the front. It is important for parents to receive proper education on car seat safety and follow the guidelines set forth by car seat manufacturers, national recommendations, and local laws and regulations.
