Expressing breast milk is the best solution for mothers who want to provide optimal nutrition for their babies even when they’re busy outside the home. However, in addition to pumping regularly, careful storage of expressed breast milk is also essential to maintain its quality, nutritional content, and hygiene.
Expressed breast milk should be stored in glass bottles, plastic bottles labeled as free of hazardous materials, or special breast milk bags. Avoid using regular bottles or plastic as they can affect the quality of the breast milk. At room temperature (27–32°C), breast milk lasts about 3–4 hours, and up to 6–8 hours in very clean and cooler conditions. If stored in a cooler bag at around 15°C with frozen ice, breast milk can last up to 24 hours. In a refrigerator at 4°C, breast milk is safe for 48–72 hours. For longer storage, a freezer at -20°C can maintain the quality of breast milk for up to 3 months.
Portion out your breast milk into small portions to avoid wastage, and always label each container with the date of expression. Make sure not to overfill the container to prevent expansion during freezing.
