My son is refusing defrosted breast milk, what now? We frequently do see that the defrosted breastmilk is not happily taken and the reason is normally the defrosting method. If breastmilk is defrosted too quickly by heat then parts of the milk sour before other parts are fully defrosted. If breastmilk is defrosted out the fridge too slowly it may also cause some souring if the room temp is too warm. The best way to defrost breastmilk is in small quantities in the fridge overnight and prior to feeding leave at room temp for 1\2 to 1 hour depending on how cool or warm it is.
