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?

Rationale: A. Start using a highchair for feedings: Infants typically begin using a highchair around 6 months of age when they can sit unsupported. At 3 months, using a highchair is unsafe as the infant lacks sufficient head and trunk control. B. Place no more than one small pillow in the crib: Pillows and soft bedding increase the risk of suffocation and sudden infant death syndrome (SIDS). The safest practice is to keep the crib free of pillows, blankets, and other soft items. C. Make sure the crib mattress is soft: A firm crib mattress is recommended to reduce the risk of suffocation and SIDS. A soft mattress can create indentations that pose hazards for infants. D. Remove bibs when the infant is going to sleep: Bibs can become choking or strangulation hazards during sleep. Removing them before sleep reduces the risk of airway obstruction and promotes infant safety.
