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

A. "I should place a rolled blanket along each side of my baby's head in the car seat.": Adding blankets around the newborn’s head can interfere with proper harness fit and may increase the risk of suffocation or injury during a crash. Blankets should be placed over the harness, not underneath or beside the infant. B. "I should place my baby's car seat rear-facing until 2 years of age.": The American Academy of Pediatrics (AAP) and the National Highway Traffic Safety Administration (NHTSA) recommend that all infants and toddlers should ride in a rear-facing car seat until they are at least 2 years of age or until they reach the highest weight or height allowed by their car seat manufacturer. This position provides the best support for the child's head, neck, and spine in the event of a crash, which is critical since a newborn's neck muscles are not yet strong enough to support their relatively large head during sudden deceleration. C. "I should put the car seat retainer clip at the level of my baby's belly button": The harness retainer clip should be positioned at the level of the infant’s armpits (chest level), not at the belly button, to keep the straps properly positioned over the shoulders. D. "I should position my baby's car seat at a 90-degree angle in the car.": Newborn car seats should be reclined at about a 45-degree angle to prevent the head from falling forward and obstructing the airway, rather than upright at 90 degrees.
