After the storage time has passed, throw out the breast milk. Use the container with the earliest date first. Once it has begun to thaw, run warm water to finish thawing. Never thaw at room temperature. Warm breast milk by placing the container in a bowl of very warm water.
Many babies take expressed breast milk well when fed with a cup or spoon.
Hold your baby when feeding expressed breast milk. Make feedings an enjoyable time for you and your baby. Talk to your baby and give lots of smiles. Burp your baby as needed. Throw away any breast milk that your baby does not drink after each feeding.
