You can take medicine when you have a cold while breastfeeding, but you need to be careful to avoid taking the medicine on your own. Since some cold medications can be excreted through breast milk and may affect your baby, you need to pay attention to going to a regular hospital and also need to clearly state that you are breastfeeding. If you take drugs that can be excreted through breast milk, you need to pay attention to stop breastfeeding until the drugs are excreted, which is about three days after you stop taking the drugs. Breastfeeding women need to pay attention to wear a good mask after a cold to avoid infecting the baby, because respiratory infections are somewhat contagious, especially need to pay attention to avoid kissing the baby, keep indoor air circulation. Also need to pay attention to drink more water, more excretion, help the recovery of the disease, pay attention to strengthen the intake of nutrients, pay attention to good rest, avoid staying up late.
