Preterm infants, or those born before 37 weeks of gestation, have higher nutritional needs compared to full-term infants. Key nutritional strategies include: - Breast Milk Fortification: Breast milk is ideal, but it may need fortification to meet the higher protein, calorie, and mineral needs of preterm infants. - Parenteral Nutrition: In cases where enteral feeding is not possible, nutrients are delivered intravenously. - Specialized Formulas: Preterm formulas are designed to meet the specific needs of these infants.
