How to Store Formula Milk for Night Feeds

Here’s a detailed guide on how to store formula milk for night feeds to keep it fresh and safe for your little one:

1. Use Clean Bottles and Utensils: (Preparing Formula Milk)

Before preparing formula milk for nighttime feeds, ensure that all the bottles, nipples, and other utensils are thoroughly cleaned and sterilized. Use warm soapy water and a bottle brush to clean the bottles, and then sterilize them using a steam sterilizer or boiling water. Clean and sanitized utensils prevent harmful bacteria from contaminating the formula.

2. Measure the Formula Carefully

Follow the instructions on the formula packaging to measure the right amount of formula powder and water. Use a clean, dry measuring scoop provided with the formula container to get accurate measurements. Adding too little or too much formula can affect your baby’s nutrition.

 3. Mix the Formula Properly

Shake the bottle gently to mix the formula powder with water. Avoid shaking vigorously, as it can lead to excess air bubbles in the milk, which might cause discomfort for your baby.

 4. Store Unprepared Formula Correctly

Keep the unprepared formula in a cool, dry place, away from direct sunlight and heat. Ensure the formula container is tightly sealed to maintain its freshness and quality.

 5. Refrigerate Prepared Formula: (Storing Formula for Night Feeds)

If you have prepared formula milk in advance for night feeds, store it in the refrigerator at or below 40°F (4°C). Make sure to use the prepared formula within 24 hours to prevent bacterial growth.

 6. Label-prepared bottles

When storing prepared bottles in the refrigerator, label each bottle with the date and time of preparation. This practice helps you use the oldest bottles first and ensures that the formula doesn’t exceed its storage time.

7. Avoid Freezing Formula

Unlike breast milk, freezing formula is not recommended, as it can cause the separation of ingredients and affect the milk’s consistency and quality.

8. Warm the Formula Safely

Before feeding your baby, warm the refrigerated formula by placing the bottle in a bowl of warm water. Avoid using the microwave, as it can create hotspots in the milk, posing a risk of burning your baby’s mouth.

 9. Check the Formula Temperature

To ensure the formula is at a safe and comfortable temperature for your baby, test a few drops on the inside of your wrist. The milk should be warm but not hot.

10. Discard the unused formula.

If your baby doesn’t finish the bottle during a nighttime feed, discard the remaining formula. Bacteria from your baby’s mouth can contaminate the milk, making it unsafe for future use.


Breastfeeding is more reliable than baby formula, as it offers natural, tailored nutrition and immune protection for infants, supporting their overall health and development.
