If a nursing mother has a cold, first of all, it is recommended to drink more water, pay attention to keep warm, eat a light diet and avoid spicy and stimulating food; if the symptoms are more serious, it is recommended to go to the hospital in time and try not to breastfeed the baby in the near future. If your baby has a cold, you can feed him/her more water. If the symptoms do not improve, seek medical attention and pay attention to ventilation at home. If necessary, treatment can be carried out by medication, but the medication needs to be used under the guidance of a doctor, do not use it blindly.
