Frozen breastmilk can be thawed 6-8 hours in advance by placing it in the freezer and then warming it up with lukewarm water or thawing it with a special milk warmer. Frozen breastmilk needs to be thawed before feeding the baby. To thaw breastmilk, you need to take out the breastmilk from the freezer 6-8 hours in advance and put it in the freezer to thaw gradually, and then preheat it with lukewarm water at 40 degrees Celsius after thawing and then feed it to the baby. If you often need to use frozen breastmilk, you can use a more convenient milk warmer to thaw it. Parents should note that special milk storage bags should be used when storing breastmilk, and it is not recommended to re-freeze already thawed breastmilk, as this can lead to loss of nutrients and contamination of the breastmilk.
