The nurse is educating the caregivers of an 8-month-old infant who has frequent nighttime awakenings and difficulty falling asleep. Which recommendation should the nurse prioritize to improve the infant's sleep patterns?

A. Limiting social interactions to reduce overstimulation during early infancy: While minimizing overstimulation is sometimes necessary, limiting social interaction can hinder the development of trust and attachment, which are critical psychosocial milestones at 4 months.

B. Responding promptly and calmly when the infant cries to foster trust and security: At 4 months, infants are developing a sense of trust versus mistrust. Consistent, sensitive responses to the infant’s needs help establish secure attachment and a foundation for healthy psychosocial development.

C. Encouraging the infant to explore objects independently without interaction: Independent exploration is limited at this age, and social interaction is crucial for developing attachment and communication skills, so this does not support expected psychosocial milestones.

D. Allowing the infant to cry for extended periods to encourage self-soothing: Infants this young are not developmentally capable of self-soothing for long periods. Ignoring their cries can undermine trust and security, which are central at this stage.

A. "Avoid giving any new foods until after the infant is one year old to prevent allergic reactions.": Delaying the introduction of solid foods beyond 6 months is not recommended and may increase the risk of nutrient deficiencies and feeding difficulties. Early, age-appropriate introduction is safe and supports growth.

B. "It's best to begin solid foods at 4 months to help reduce the amount of breast milk or formula intake.": Introducing solids before 6 months is generally not advised as the infant’s digestive system and oral-motor skills may not be fully developed, increasing the risk of choking and nutrient imbalance.

C. "Solid foods should complement breast milk or formula starting around 6 months, but table foods should only be introduced when the infant shows readiness signs like grasping.": Evidence-based guidelines recommend starting solids around 6 months, continuing breast milk or formula, and assessing readiness cues such as head control, sitting with support, and interest in food. This approach promotes safe feeding and nutritional adequacy.

D. "You can replace breast milk entirely with solid table foods once the infant reaches 6 months of age.": Solid foods at 6 months are meant to complement, not replace, breast milk or formula, which remain the primary source of nutrition until around 12 months.
