Breastmilk can be eaten after refrigeration if it is stored correctly. Separation of water and milk generally refers to the layering of breastmilk, which is a normal phenomenon. Because breast milk is rich in nutrients, including protein and fat content is relatively high, so usually in the constant temperature conditions, fat and protein is dissolved in the milk, the general phenomenon of layering will not occur. But due to the freezing in the refrigerator, with the prolongation of time, because of the density and other reasons, then the fat and protein in the milk, water quality and so on will be separated from the line of stratification, the phenomenon of separation of water and milk. If this is the case, you can first take out the milk, and then put it in a room temperature environment, so that the milk to return to room temperature, and then put it in a milk warmer to heat up, the protein and fat will be dissolved in the milk again, and the phenomenon of stratification will disappear, and at this time you can breastfeed your child again. However, it is important to note that if the milk is not stored in the correct way and then appears to have spoiled, it is recommended not to consume it.
