Frozen milk cannot be refreezed again. Thawed frozen milk should be consumed within 24 hours or earlier. dont let your ebm go to waste. A friend of mine used to have so much supply she gave her baby ebm bath. She claimed it acts like "lotion", nourishing to baby skin.. I've tried it before once or twice.. For me I dont feel much of a difference, but since your ebm cannot refreeze y not try this so your ebm won't be wasted if baby cannot finish all your thawed milk within 24 hours..
