To extend storage, freezing is an option. Consider the type of freezer you have and its location. If your fridge has a separate freezer compartment, frozen milk is suitable for three to four months. However, if the freezer is inside your refrigerator, the storage time reduces to about two weeks. Employing a standalone deep freezer allows you to store expressed breast milk for six months or even longer.

How to use stored breast milk?

Initiate the thawing or warming process of breast milk by running it under warm tap water for a few minutes. Alternatively, gently swirl the container in a bowl of warm water. Once warmed, assess the milk's temperature by placing a droplet or two on your wrist. If the milk feels comfortably warm and not hot, it's suitable for your baby.

Refrain from offering hot milk; allow it to cool down if necessary. Babies can consume cold or room temperature milk, though their preferences may vary. Avoid using a microwave to heat breast milk due to uneven heating, scalding risks, and potential damage to essential nutrients.

Similarly, don't warm a milk container directly on the stove. Instead, heat a pan of water on the stove, remove it, and then place the container in the warm water. Excessive heat may diminish some nutrients, so avoid boiling or reaching high temperatures.
