Breastmilk drawn from a breast pump can be kept at room temperature or placed in the refrigerator’s freezer or refrigerator, but the duration of breastmilk storage varies with different storage methods. Breastmilk from a breast pump can be kept at room temperature if the child can consume it within 2 to 3 hours. However, be careful that the container in which the breastmilk is kept must be clean. If the child can consume it within 2~3 days, you can store it in the freezer of the refrigerator after putting it in a clean container. However, if the child will consume it within 6 months, it can be stored in the freezer of the refrigerator. When storing breastmilk, be sure to keep the container holding the breastmilk clean and hygienic, and label the date and time of the breastmilk on the outside of the container to prevent the breastmilk from spoiling and affecting your child’s health.
