How long is breast milk stored in the refrigerator after pumping

Breastfeeding mothers frequently have to pump and freeze milk for later use, particularly when juggling other obligations like work and rest. Keeping babies healthy and fed requires knowing how long breast milk can be safely kept in the refrigerator.

If you store milk properly, it will keep its nutrients and be safe for your baby. The guidelines for how long it can be refrigerated, however, can change based on a number of variables, such as how the milk is handled after pumping and the refrigerator’s temperature.

This post will walk you through the fundamentals of storing breast milk so you can plan ahead with confidence and don’t waste this valuable resource.

The need to store breast milk

The amount of useful components in milk increases with decreasing storage time. Because of this, feeding the infant with a freshly expressed product is better than storing it in the freezer or refrigerator. But sometimes life presents an opportunity to breastfeed the child—for instance, when the mother must go for an extended period of time—or presents an excessive amount of it. It is necessary to have storage during these times.

Basic rules for storing breast milk

General guidelines for preserving expressed milk to prevent spoilage:

• use airtight containers made of safe materials;
• sterilize containers before use;
• do not leave bottles in hot places for more than 3 hours;
• be sure to warm up milk using suitable methods before use;
• send the product for storage as soon as possible after pumping.

In the refrigerator

A lot of people would rather store breast milk containers in the refrigerator. Since the door is always opening and the temperature will fluctuate, do not place containers on top of it.

Generally speaking, the product should be refrigerated.

• place milk in the refrigerator as soon as possible after pumping;
• store in glass, plastic bottles or special bags;
• it is permissible to add expressed milk to a container with liquid that is already stored in the refrigerator, if it is pre-cooled.

The chosen container and its placement within the chamber thus have a major influence on how long breast milk is kept in the refrigerator.

In the freezer

The general process of storing in a freezer and a refrigerator is the same. But there are a few unique characteristics:

• Do not use glass or plastic bottles, they may crack or burst;
• The lid or bag must be tightly sealed;
• You cannot freeze freshly expressed warm milk, let it stand on the top shelf of the refrigerator first;
• Do not fill containers more than ¾ full, because the product will increase in volume when frozen;
• It is advisable to store milk in small portions, no more than 60–90 ml, this way it is much more convenient to measure out the required amount.

At room temperature

The season and the existence of any heating equipment can affect the room’s air temperature. At a given moment, you should pay close attention to the thermometer readings. The milk will not last longer than two to three hours if the room is hot and the temperature gauge reaches 26 degrees. The container needs to have a lid and be sterile and airtight.

Shelf life of breast milk

The conditions selected will determine how long breast milk can be stored:

• At room temperature. The shelf life in this case is extremely short. This is especially true for hot summer days, when the air temperature rises to 26 degrees and above. In this case, the milk will last no more than 3 hours, and then will begin to sour and spoil. If the room temperature does not exceed 24-25 degrees, the product will last up to 8 hours. In this case, it is necessary to place it in a sterile glass bottle with a sealed lid. However, it is not prohibited to store milk in specialized plastic containers or bottles.
• In the refrigerator. The shelf life is up to a week. It is also important that the temperature inside the refrigerator does not exceed 7 degrees. It is advisable to place the container on the top shelf closer to the wall. In no case should you put the bottle on a door that is constantly opened.
• In the freezer. Storage periods vary due to the characteristics of different refrigerator models. If the temperature in the freezer is -6–8 degrees, milk will last in a sealed sterile container for up to six months. At -18 degrees and below, you can leave the natural product for a year. However, it is worth remembering that when frozen, milk gradually loses the beneficial properties that only fresh liquid has. In addition, before use, it is necessary to properly defrost the product and warm it up.

After pumping, breast milk can be kept safely in the refrigerator for up to four days, but it is best used within three days for safety and quality reasons. In order to ensure that your baby receives the maximum benefit from the stored milk, keep it in an airtight container and store it at a temperature of 4°C (40°F) or lower. This will help preserve the milk’s nutrients and inhibit the growth of bacteria.

Containers for storing breast milk

A natural product’s safety is contingent upon the container it is stored in. Popular choices:

• glass jars;
• plastic bottles;
• special plastic containers;
• freezer bags.

For new mothers, the first choice is thought to be the most advantageous and ecologically friendly. If the milk is only going to be kept for a week or less, glass containers are used. Never allow glass to freeze its contents. Such a product will almost certainly cause cracks to show up in the walls when heated.

Additionally, plastic bottles work best when cooled rather than frozen. The liquid actually expands in volume and has the potential to burst when its aggregate state changes.

Storing breast milk in designated plastic containers is still the most effective method. The dishes won’t break or release any harmful materials, even when exposed to the lowest temperatures. Reusable containers that last a long time are available at most stores catering to young mothers and babies.

Single-use, sealed freezer bags are highly common. They don’t occupy a lot of freezer space. Additionally, they have a unique scale that lets you measure out how much milk you require. In a separate window, the freezing date is written. A tight lock prevents foreign odors from entering the bags.

The following specifications must be met by the dishes used to store breast milk:

• Sterility. If the containers are reusable, they should be thoroughly cleaned each time before use.
• Tightness. If air gets to the product, this will significantly reduce its shelf life.
• Absence of toxic substances in the composition of the material from which the container is made. Harmful components should not be released during heat treatment.
• Presence of a scale for determining the volume of liquid.

Your baby’s breast milk is an important source of nutrition, and keeping it safe and hygienic is dependent on how you store it. Freshly pumped milk can keep for several days in the refrigerator, but it must be stored carefully to prevent spoiling.

Make sure to mark milk with the date of expression on the label so you can use the oldest milk first. To maintain a constant temperature, store it in the refrigerator’s coldest section rather than in the door. To protect your baby’s health, it is best to throw away any milk that you aren’t sure is fresh.

Even if you are unable to breastfeed your child directly, you can still give them healthy meals by storing breast milk according to recommended guidelines. You can maximize your efforts and feel at ease with safe storage.
