What is the Recommended Duration and Temperature for Storing Breast Milk?

What Containers Should I Use to Store My Breast Milk?

When choosing containers for storing your breast milk, the right material is important to retain its nutrients and ensure your baby gets the most benefit from it.
• Glass containers and polypropylene containers are ideal as they are safe for repeated use and help preserve the nutritional value of your milk.
• Special breast milk storage bags are a convenient and space-saving option, ideal for freezing milk. However, it is recommended to use these bags only once. Reusing storage bags can pose an infection risk
Avoid using steel, polyethylene, and BPA-containing containers as they may degrade the beneficial cells in breast milk that support your baby’s immunity.

How Should I Label Stored Breast Milk?

Properly labeling your breast milk ensures that you use the oldest milk first, keeping it fresh and reducing waste. For each container of stored milk, be sure to label:
The date and time the milk was expressed.
Always use the oldest milk first to make sure it stays fresh and safe for your baby.

How Should I Clean Breast Pump Parts and Storage Containers?

Proper cleaning of breast pump parts and storage containers is crucial to prevent contamination. Here are steps to ensure safe cleaning:

• Dismantle all equipment: Take apart the pump parts, bottles, and other components for thorough cleaning.
• Wash with hot, soapy water: Use hot, soapy water to clean all the parts and storage containers. Rinse thoroughly to remove soap residue.
• Ensure everything is completely dry: Allow the components to air dry or use a clean towel to dry them completely before storing.
• Avoid chemical disinfectants: Do not use chemical disinfectants on the pump or containers to the extent possible, as they may leave harmful residues that could contaminate the milk. Stick to simple soap and water for effective cleaning. Chemical disinfectants may be used when clean water is unavailable.

Additional Tips for Safe Breast Milk Storage and Handling

• Thawing Milk: Always thaw frozen breast milk in the refrigerator or by placing it in warm water. Never microwave breast milk as it can lead to hot spots that may burn your baby and change the nutrition value of the milk.
• Avoid Refreezing: Never refreeze milk that has already been thawed.
• Storing Milk for Travel: Use insulated coolers with ice packs for short trips to store milk at a safe temperature until you can refrigerate it.
• Mixing Milk from Different Pumping Sessions: It is best not to mix milk from different pumping sessions to maintain optimal freshness and safety. However, if mixing is necessary:
– Ensure the milk is cooled to match the temperature of the stored milk before combining.
Always label the mixed milk with the date of the oldest milk in the batch.

How to Identify Milk That’s No Longer Safe?

Scent

Fresh breast milk typically has a sweet or slightly soapy smell. If it develops a sour or rancid odor, this is a strong indicator that the milk has gone bad. However, some mothers may notice a sour smell due to high lipase activity, which can alter the scent without indicating spoilage.

It is important to learn the smell of your own freshly expressed milk so that you can identify any changes that might suggest spoilage or other issues.

What is The Ideal Milk Temperature for Babies?

Key Points on Milk Temperature

  • Preferred Range: Babies generally prefer milk warmed to between 97.7°F and 99.5°F (36.5–37.5°C). This temperature closely imitates the natural warmth of breast milk.
  • Testing the Temperature: To ensure the milk is safe, place a few drops on the inside of your wrist. It should feel warm but not hot. If it feels cold, warm it a bit longer; if hot, let it cool before feeding.
