Milk should not spoil before the times listed above, but the longer milk is stored, the more nutritional value is lost.

The living parts of a mother's milk kill bacteria, making it much hardier and longer-lasting.

This is general information and does not replace the advice of your physician or healthcare provider. If you have a problem you cannot solve quickly, seek help right away.

Every baby is different, and your baby may not be average.
If in doubt, contact your physician or other healthcare provider.
