It is necessary to eliminate residual milk after weaning. At the end of the lactation period, the child needs to be fed back after weaning. Usually, you need to take Huinaibao orally, or take a large amount of vitamin b6 and malt-based foods. You can choose to decoct malt in water. After weaning, there will be milk stasis. Patients can use a breast pump to suck out the accumulated milk in time, and then wear a suitable bra to avoid mastitis caused by milk engorgement, squeezing and other reasons. Mastitis usually presents with localized redness, swelling, heat and pain, which requires anti-inflammatory treatment.
