Whether a full-term baby with a cold and congestion can heal on its own depends on the specific situation and cannot be generalized. Some full-term babies with colds have mild symptoms and can heal on their own. Because the cold is a self-limiting disease, the general course of the disease is 5-7 days. Cold is a process of increasing resistance for infants and toddlers. If infants and toddlers have mild nasal congestion or runny nose symptoms, they can temporarily avoid taking medicine and increase water intake appropriately, adding water once between milk, the nasal congestion symptoms can gradually return to normal. If your baby has a cold with other symptoms such as poor appetite, drowsiness, fever and other symptoms in addition to a stuffy nose and runny nose, the situation is more serious and may be caused by a viral infection, which usually cannot be cured by itself, so you need to consult a doctor in time to check the relevant indicators and treat the symptoms to prevent the disease from progressing to pneumonia and other diseases. During the cold period, parents should pay attention to keeping the baby warm. If there is nasal congestion, you can use a hot towel on the root of the nose, and you can also raise the head and shoulders when the child is feeding to improve the nasal congestion.
