So, how long is milk good for after warming? More than 24h?

Many moms prefer to use the pump and store their breast milk for various reasons. It may be due to sore nipples from breastfeeding, or because of too much milk production that they pump and save their milk for future use. And when you get the milk out of the fridge to feed your baby, you will need to warm it up for them to drink it properly.

How Long is Breast Milk Good For After Warming

But take note that breast milk has a lifespan once you have warmed it up and fed your baby. While fresh breast milk can stand at room temperature (60 to 85 degrees Fahrenheit) for up to eight hours, thawed and warmed milk has a different timeframe, depending on how you collected the milk and how it was thawed.

On average, thawed grease milk can stay in the fridge (if there are some unconsumed left) for up to 24 hours. Make sure to put the warmed milk back in the fridge for half an hour for you to be able to reuse it again. If so, you can rewarm it to feed your baby again.

If it has been over 24 hours and your warmed milk in the fridge still sits, then it’s best to throw it out and avoid reusing it to prevent any form of bacteria from coming in your baby’s body. Avoid using rewarmed milk to babies who are ill or have a weak immune system.

How to Know If Breast Milk is Soiled

Besides the lifespan of breast milk after warming it up, here are the expiration dates of breast milk depending on how you store it:

  • Fresh breast milk in the fridge will last for three to eight days.
  • Frozen breast milk will stay fresh for up to two weeks in a fridge with a single door to both freezer and refrigerator.
  • For refrigerators that have a freezer with a separate door, it will last for three to six months.
  • In a deep freezer or chest, breast milk can last for six months up to a year, as you don’t open it as many times as freezer doors in the fridge.
  • If the breast milk sits longer than these periods, then throw it out to avoid accidentally feeding your baby the spoiled milk.

You will know if breast milk is soiled if it is separated into two layers even after swirling it around. The scent is also a high indicator. If it smells rancid like spoiled cow’s milk, then consider it unusable. Another factor to consider would be its flavor. Soiled breast milk will have a very sour taste. So if any of these apply to your breast milk, throw it away immediately.
