1. Collecting Breast Milk:

When pumping breast milk, it’s crucial to follow a few key steps to ensure cleanliness and minimize contamination:

a. Wash your hands thoroughly with soap and water before expressing milk.
b. Sterilize the pumping equipment (bottles, breast shields, valves, and membranes) before each use.
c. Use clean storage containers that are specifically designed for breast milk, such as BPA-free bottles or breast milk storage bags.

2. Safe Storage Guidelines:

Proper storage is vital to maintain the nutritional value of breast milk and prevent the growth of harmful bacteria. Here are some guidelines to follow

a. Freshly expressed breast milk: If you plan to use the milk within a few hours, store it at room temperature (between 16-25°C or 60-77°F) for up to four hours. Keep the container covered and away from direct sunlight.

b. Refrigeration: For longer storage, place the expressed milk in the refrigerator, which should be kept at a temperature of 0-4°C (32-39°F). It is advisable to store milk in the back of the refrigerator, as the temperature there is more stable. Freshly expressed breast milk can be refrigerated for up to four days. However, using it within three days is ideal for maintaining its quality.

c. Freezing breast milk: If you won’t be using the milk within a few days, freezing is the best option. It helps preserve the milk’s nutrients for an extended period. Use these guidelines when freezing breast milk:

   – Use freezer-safe, BPA-free containers or breast milk storage bags specifically designed for freezing.
   – Leave some space at the top of the container or bag to allow the milk to expand during freezing.
   – Label each container or bag with the date of expression to ensure proper rotation.
   – Place the containers or bags in the coldest part of the freezer, away from the door, to maintain a constant temperature.
   – Frozen breast milk can be stored for up to 6-12 months. However, using it within six months is recommended to ensure optimal quality.

3. Thawing and Warming Breast Milk:

When it’s time to use the stored breast milk, it’s crucial to thaw and warm it properly to maintain its nutritional value and minimize the loss of beneficial components:

a. Thawing frozen breast milk: There are a few safe methods for thawing breast milk:

   – Refrigerator: Transfer the frozen milk from the freezer to the refrigerator and allow it to thaw slowly. This method takes approximately 12-24 hours, depending on the amount of milk.
   – Running water: Hold the container or bag of frozen breast milk under cool or lukewarm running water until it reaches room temperature.
   – Bottle warmer: Use a bottle warmer specifically designed for breast milk to thaw and warm the milk gradually.

b. Warming breast milk: Never use a microwave to warm breast milk, as it can create hotspots that may scald your baby’s mouth.
