Breastmilk is best stored in special milk storage bags in a room temperature environment, refrigerated environment or frozen environment, and the milk is warmed up when used. Usually, if a mother cannot feed her child directly or if she has too much breastmilk, she can store it. It should be stored at room temperature for no more than 2 hours; in a refrigerated environment for up to 24 hours; and in a frozen environment it can often be stored for 3 to 6 months to maximize the use of breastmilk for feeding the child. When it is time to breastfeed your child, you can remove the stored milk and warm it. This is usually done by placing the milk in a milk warmer and heating it, often to about 40°C. If the heating temperature is too high, the nutrients in the milk may be destroyed, leading to a decrease in nutrient content, which can affect the child’s nutritional supply. In addition, when storing breastmilk, pay attention to the cleanliness and hygiene of the items you touch to avoid contaminating the milk, and seek medical attention if you become unwell after drinking contaminated milk.
