Breastfeeding babies with colds are ineffective and can have side effects on the baby and affect the baby’s healthy growth. Many people believe that if a breastfeeding mother takes medicine, the medicine will be better absorbed by the mother and passed to the baby through breast milk, so that the baby can be treated faster, its no scientific basis, and may even have a negative impact on the baby. Because the drug will lose its own efficacy after metabolism, what will be passed to the baby through breast milk may only be drug toxins and side effects that will affect the healthy growth of the baby and even irreversible situation. The correct way should be to administer the medication to the baby itself, and it simply cannot be replaced through the mother.
