How Long After Thawing Breast Milk Can It Be Used?

As soon as you thaw the breastmilk, it is vital to use it within 24 hours if you defrost it in the fridge. You will count these 24 hours once the milk is thawed and not once you take it out of the freezer. As soon as you bring the breastmilk to room temperature, it will stay good for two hours.

The FIFO rule means first in-first out. So, you will start thawing the first milk you added to your freezer. By doing so, you reduce the risk of having expired breastmilk, and you will use your storage more wisely^[2]. However, to do so means that you should add a date on your breastmilk container before you put it in the freezer, so you know which one is the oldest when you need to thaw it.

The best way to thaw breastmilk is in the fridge. All you have to do is move the breastmilk container from the freezer to the fridge and allow it to sit there for about 12 hours. Once your breastmilk is thawed in this manner, you can use it for the next 24 hours. So, it is essential to not thaw more breastmilk than your child eats in a day, taking into account the night meals.

If you want to speed up the thawing process, you can do that by using lukewarm water. You can let lukewarm water run on the container of breastmilk, being it a bottle or a bag. The water should have a temperature of a maximum of 39 degrees C or 99 degrees F. Depending on the size of your breastmilk container, this method of thawing could take 20 minutes or more.

During both the freezing and thawing process, the fat in the breastmilk will separate from the rest of it and rise on the surface. Therefore, you will see the fat as the first layer of breastmilk in your container. To mix the fat with the rest of the breastmilk, you will have to swirl the bottle once the milk is completely thawed. Make sure to serve it to your baby after you swirl it, as soon as possible, before the layers of the breastmilk start to separate again.

Microwaving breastmilk might seem like a rapid method to thaw it and warm it up as you need. But this is the worst option you can choose. The microwave will reduce the nutrients in your breastmilk significantly. On top of that, the microwave will not heat the milk evenly. There will be hot spots in the container, which can harm your baby's throat as they drink the milk. This anti-microwave rule applies to baby formula as well as other types of milk as well.

Also, avoid putting the container of breastmilk in boiled or boiling water. The big temperature difference will also reduce the nutrients of the breastmilk, and hot spots could also appear in this case.
