First of all, sucking milk. During the working period, mom should make sure to suckle every 3-4 hours, which can effectively reduce the uptake of milk as well as maintain the amount of lactation. The second, and more important step, is milk storage. It is best to store breastmilk in one portion of about 100ml. Where the mom works, there must be a place to store human milk. Also when storing the milk after pumping, it is important to write a label on the bottle and record the time, so that it is easy to store, as well as to feed the baby later. Step 3, Thawing. For thawing, use a sealed plastic bag, put the cold milk inside, and gradually add warm water outside the bag until the breastmilk has thawed to a more suitable temperature for feeding your baby. Never put breastmilk directly into the microwave or oven for direct heating, as this heating will destroy the nutrients in the breastmilk. As a final step, put the breastmilk at the right temperature into a bottle and feed it to your baby. In general, thawed breastmilk must be eaten within 24 hours, and the milk cannot be thawed again after thawing.
