Which instruction should a nurse suggest to enhance the discharge teaching plan for a postpartum client?

A firm mattress in the newborn's crib is recommended to enhance safety and reduce the risk of sudden infant death syndrome (SIDS) and other sleep-related fatalities. Firm mattresses provide the necessary support for the infant, helping to maintain an open airway during sleep. Soft mattresses, pillows, and any loose bedding can pose a suffocation hazard, increase the chances of overheating, and may disrupt the safe sleep environment recommended by pediatric health organizations.

In the context of discharge teaching, emphasizing the importance of using a firm mattress aligns with best practices for infant sleep safety. It is critical for new parents to understand that creating a secure and safe sleeping environment for their newborn is a top priority in ensuring their infant's health and well-being.
