Thawing and warming of breast milk

Frozen EBM must be warmed quickly but NOT in boiling water, as the milk will curdle.

DO NOT leave EBM to stand at room temperature to thaw.

Place the container under running cold water. Gradually make the water warmer until the milk becomes liquid.

Warm the container of chilled or thawed EBM in a jug of hot water until it is body temperature.

Microwave ovens should NEVER be used to thaw or heat milk. Their safety is unknown and heating is uneven.

EBM cannot be reheated if your baby doesn’t finish the feed – so warm only a small amount at a time.

Note:

Thawed EBM:

  • That has not been warmed can be stored in the refrigerator for 24 hours
  • That is not refrigerated must be used within four hours
  • Must not be re-frozen
