A nurse is reinforcing teaching about home safety precautions with the parents of a 3-month-old infant. Which of the following instructions should the nurse include in the teaching?

A. Place no more than one small pillow in the crib: Infants under 12 months should not have pillows in the crib due to the risk of suffocation or sudden infant death syndrome (SIDS). Crib sleep surfaces should be firm and free of soft bedding. B. Remove bibs when the infant is going to sleep: Bibs can pose a strangulation or suffocation hazard if left on while the infant sleeps. Removing bibs ensures a safe sleep environment and reduces risk of accidental injury. C. Start using a highchair for feedings: Highchairs are not recommended until the infant can sit independently, typically around 6 months. Using a highchair too early increases the risk of falls and injury. D. Make sure the crib mattress is soft: A soft mattress increases the risk of suffocation and SIDS. A firm, flat mattress is the safest sleep surface for infants under 12 months.
