A 4-month-old infant with a ventricular septal defect who has poor weight gain; what dietary change is recommended?

• A. Adding solids to the diet
• B. Fortifying breast milk to increase calories
• C. Stopping breastfeeding and giving 30 kcal/ounce formula
• D. Supplementing breastfeeding with 24 kcal/ounce formula

Answer: (B)

Infants with a congenital heart defect like a VSD often have higher energy needs and may fail to gain weight if feeds don’t supply enough calories per bite. The goal is to boost calories without increasing the volume of fluid the heart must handle. Fortifying breast milk adds calories directly to the milk, so each ounce provides more energy while keeping the total volume the same. This helps weight gain without risking fluid overload or overly concentrated feeds. Introducing solids at four months isn’t recommended developmentally and carries choking and digestion risks. Switching completely to a high-calorie formula with an unusually high density (such as 30 kcal/oz) isn’t ideal as the first step and bypasses the benefits of continuing breast milk; if a formula change is needed, a standard high-calorie option (about 24 kcal/oz) is typically used.
