It is best not to continue to give your child breast milk after it has been heated to avoid the effects on the child’s body. Breast milk contains a lot of protein, sugar and other substances, and after heating it, a lot of protein will be decomposed, resulting in protein loss and also destroying other components, so after the child consumes it once, the nutrition in it has become very little, so if you give it to the child again, it will not play a good role, and it may also lead to diarrhea and affect the child’s metabolism. It is important to note that there are certain microorganisms in the heated breast milk, the heating temperature is difficult to kill the bacteria, so the microorganisms will begin to multiply, if put back into the refrigerator may lead to an increase in microorganisms, into the baby’s body will lead to a variety of diseases, so the unfinished breast milk can not continue to keep.
