It is not normal for a baby to cough a few times a day. Dry cough brings a more serious danger and there are more babies and young children who show symptoms of occasional dry cough. This should be brought to the attention of the baby’s mother and can damage the baby’s health. There are many causes of occasional dry cough: when a baby is stimulated by cold air, it is very easy to develop a dry cough. Cold air can irritate the mucous membrane of the baby’s respiratory tract, resulting in congestion, edema, and an exudative response that induces a dry cough reflex. It does not start as a microbial infection, but its long-term onset can induce the appearance of secondary viral and bacterial infections, leading to particularly serious damage to the baby’s health. There is also allergic dry cough. Many babies are allergic and are prone to allergies, which increases the chance of occasional dry cough and even affects the baby’s breathing, causing more pain, mainly due to the stimulation of antigens and non-antigens. Especially during the pollen season, it is easy to develop allergies that can lead to dry cough. Therefore, mothers should pay extra attention to keep their babies away from allergens. After the symptoms of dry cough appear, it is also important to seek early medical treatment to find the cause and start targeted treatment. It is recommended that if the body temperature is normal and the cough is not aggravated, no medication can be used, but attention should be paid to keeping the baby warm and protected from cold, so that the cough can be relieved naturally. If the cough worsens and the body temperature is higher than 37.5℃, you need to go to the local hospital. As long as you actively seek medical attention, your baby’s dry cough will not cause any major problems.
