How To Keep Stored Breast-milk Fresh?

Breast milk remains fresh even after a tenure of 3-5 days – but only if it is stored in a cooler area. In hot areas, even after refrigerating milk, it has the tendency to lose its freshness, as the fridge constantly gets opened and closed. Breast milk must always be stored at the back of the freezer behind other items, and never near the door. When you consistently open your freezer for some reason or the other, breast milk will not get receptive to the changing temperature conditions. The below pointers can help in keeping stored breast milk fresh for longer periods:

  • If you have to use it within 4-5 hours of expressing your breast milk, then you may store it at room temperature not beyond 25 degrees C
  • Beyond 4-5 hours, up until 24 hours, you can refrigerate it at 4 degrees C
  • You can store it in a cool box with ice-packs for upto 24 hours
  • Breast milk storage can go up to months also if it is stored in freezer with -18 temperatures

How Should I Thaw Refrigerated Breast-milk?

To thaw breast milk that has been kept in the freezer, you can move it in the freezer and it should be alright to consume. Some babies prefer cold milk, while some may like it warmed up. Run some warm water over the bad or bottle to warm the milk up. You need to use this thawed milk within 24 hours, after which it should be discarded and not refrigerated again. Once the baby has started to drink it from the bottle, use it within 1 hour of time. Because temperatures can vary at different places, it would be wise to discuss this with your doctor once.

How Much Breast-milk Can I Store In The Freezer?

A baby generally has about 2 ounces of milk at a given time, hence it is advisable to store breast milk in containers or pouches with a 2 ounce to 4 ounce capacity. You can label the containers or the bags with the date and time so that the earlier ones are used first. A covered ice tray can also be used to store small quantities of breast milk if you may need it for adding to your baby’s food once solids start. Or you can use some cubes to make one full bottle and do the math accordingly. If you opt for freezing the milk, do it as soon as you express and leave the bag or bottle somewhat empty at the top because breast milk expands when frozen.

What Precautions Should I Take When Storing Breast-milk?

If you are a working mother and plan to resume your job, you may try to get into the routine of expressing and storing breast milk before you go back.
