Maximize Your Baby’s Growth: A Guide to Making 24-Calorie Breast Milk

As a new parent, ensuring your baby’s growth and development is a top priority. While breast milk is nature’s perfect food for infants, some babies may require additional caloric support to thrive. This is where fortifying breast milk with formula powder comes into play, specifically by increasing the caloric content to 24 calories per ounce. This guide will walk you through the process of making 24-calorie breast milk, ensuring your little one receives the nourishment they need.

Understanding the Need for 24-Calorie Breast Milk

Breast milk typically contains around 20 calories per ounce, which is sufficient for most babies. However, certain circumstances may necessitate increasing the caloric density of breast milk. These include:

  • Premature infants or babies with low birth weight, who require additional calories for catch-up growth.
  • Babies experiencing slow weight gain or failure to thrive.
  • Infants with medical conditions that increase their caloric needs.

Your healthcare provider may recommend fortifying your breast milk to provide your baby with the extra calories they need without increasing the overall volume of milk consumed.

Preparing 24-Calorie Breast Milk

Making 24-calorie breast milk is a simple process that involves adding a specific amount of formula powder to your expressed breast milk. Here’s how to do it:


  • Expressed breast milk
  • Standard infant formula powder (avoid specialized formulas unless recommended by your healthcare provider)
  • Clean measuring cups and spoons


  1. Prepare the breast milk: Measure out the desired amount of expressed breast milk using a clean measuring cup. For example, if you want to fortify 3 ounces of breast milk, measure out 3 ounces (89 mL) of breast milk.

  2. Add the formula powder: Using a clean measuring spoon, add 1 teaspoon (5 mL) of standard infant formula powder to the measured breast milk.

  3. Mix thoroughly: Gently swirl or stir the breast milk and formula powder together until the powder is completely dissolved and the mixture is well combined.

  4. Feed or store: You can now feed your baby the fortified 24-calorie breast milk or store it in the refrigerator for later use.

Here’s a handy table for reference:

Breast Milk Formula Powder
3 oz (89 mL) 1 tsp (5 mL)
6 oz (177 mL) 2 tsp (10 mL)
9 oz (266 mL) 1 Tbsp (15 mL)
12 oz (355 mL) 1 Tbsp + 1 tsp (20 mL)

Note: Always follow your healthcare provider’s recommendations regarding the appropriate caloric density for your baby’s needs.

Tips and Considerations

  • Use fresh breast milk: It’s best to fortify freshly expressed breast milk to ensure maximum nutrient quality.
  • Gentle mixing: Avoid vigorously shaking or blending the mixture, as this can break down the milk’s properties.
  • Storage guidelines: Fortified breast milk can be stored in the refrigerator for up to 24 hours. Discard any unused portion after this time.
  • Warm gently: When reheating fortified breast milk, warm it gently by placing the bottle or container in a bowl of warm water. Avoid overheating or using a microwave, as this can create hotspots and destroy nutrients.
  • Consult your healthcare provider: If you have any concerns or questions, consult your healthcare provider or a lactation consultant for personalized guidance.

Making 24-calorie breast milk is a simple yet effective way to support your baby’s growth and development. By following these step-by-step instructions and adhering to proper storage and handling guidelines, you can provide your little one with the extra nourishment they need during this crucial stage of life.
