A nurse is providing teaching to a parent about sudden unexpected infant death (SUID). Which of the following statements should the nurse include?

Sudden unexpected infant death (SUID), including sudden infant death syndrome (SIDS), is associated with unsafe sleep environments and certain modifiable risk factors. Prevention focuses on safe sleep practices such as supine positioning, firm sleep surfaces, and avoiding soft bedding or overheating. Room-sharing without bed-sharing is recommended because it allows close monitoring of the infant while maintaining a separate safe sleep surface. Parental education is essential to reduce risk. Rationale: A. Using bumper pads around the crib is unsafe because they increase the risk of suffocation, entrapment, and impaired airflow. Soft bedding items are strongly discouraged in infant sleep environments. The crib should remain free of loose or padded materials to ensure safe sleep. B. Sharing a bedroom with the infant for the first 6 months is recommended because it allows the caregiver to closely monitor the infant during sleep while maintaining a separate safe sleep surface. Room-sharing has been shown to reduce the risk of SUID by facilitating early recognition of distress and promoting safer sleep practices. C. Placing the infant on a soft crib mattress after 4 months is unsafe because soft sleep surfaces increase the risk of suffocation and airway obstruction. Infants should always sleep on a firm, flat mattress covered with a fitted sheet regardless of age. Soft bedding remains a risk factor throughout infancy. D. Covering the infant with a nonflammable blanket at bedtime is not recommended because any loose bedding can increase the risk of suffocation or overheating. Instead, wearable sleep sacks or appropriate clothing should be used to keep the infant warm safely without loose coverings in the crib.
