As the nurse assigned to assess the family with an infant, what nursing interventions would you prioritize to address the risk for delayed growth in the newborn ?

Mrs. Castillo, a 30-year-old primigravida, gave birth to a healthy baby boy two days ago. She is concerned about her baby’s growth and development and seeks guidance from the healthcare team. The infant is breastfeeding well and has passed meconium but has not yet had a stool since then.
