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?

A) "I should position the car seat's retainer clip at the level of my baby's belly button.": This statement is incorrect. The retainer clip of the car seat should be positioned at the level of the baby's armpits, not the belly button. Proper placement of the retainer clip ensures the safety harness fits securely across the baby's chest, reducing the risk of injury during a crash. B) "I should keep my baby rear-facing in the car seat until she is 2 years old.": This statement is correct and aligns with current guidelines from organizations such as the American Academy of Pediatrics (AAP). Infants and toddlers should remain in a rear-facing car seat until they are at least 2 years old or until they reach the maximum height or weight limit allowed by the car seat manufacturer for rear-facing use. Rear-facing is the safest position for infants and provides the best protection for their developing head, neck, and spine. C) "I should enable the airbag when my baby is in the front seat of the car.": This statement is incorrect. Infants and young children should never ride in the front seat of a car with an active airbag, as airbags can cause serious injury or death in the event of a collision. Children should always be placed in the back seat, ideally in a rear-facing car seat, to minimize risk. D) "I should place my baby in the car seat at a 90-degree angle.": This statement is incorrect. A car seat should be installed at a slight recline to ensure that the baby's airway remains open and to prevent their head from falling forward. A 45-degree angle is typically recommended for newborns, although this can vary based on the specific car seat model and the baby's size.
