can breast milk get spoilt or become sour in the breast? is that true??

A. no dear it's not true at all it's all fake this is we called nature it never get spoiled infact even u pump out milk You can store breast milk at room temperature for 4to 5hours and in fridge for 4 to 5 days and in refrigerator you can store it up to 15 to 20 days just keep in mind do not reheat milk again and again
