Guidelines for Storage and Sterilization at Home

Storage and Sterilization

  1. Purchase some bottles and labels to store the milk. The bottles need to be boiled and sterilized before each use
  2. Clearly label each bottle, including date and time that the breast milk was collected so that you know the age of the bottle of milk.
  3. Do not overfill the bottles as breast milk expands when it is frozen.
  4. Make sure all pump material is properly cleaned and sterilized between uses.

Do not microwave breast milk. Microwaving changes the nutrient content of breast milk. To defrost frozen breast milk, run it for a few minutes under hot water, or stand the bottle in a pot of hot water where it will quickly defrost. If you have any questions regarding pumping or storing breast milk, do not hesitate to discuss them with a lactation consultant, doula or midwife.

Your breast milk is important to your babies.
