It is normal for babies to cough occasionally, but it is important to be vigilant in case of abnormalities. If your baby’s throat is dry and the house is hot, it is easy to have a few coughs occasionally, but there is no need to worry too much. If the cough is continuous and the baby is holding his breath, parents should pay attention to the fact that the child’s respiratory tract is not immune and that smoking in the home can stimulate the child’s nasopharynx and lead to coughing, so it is important to go to the hospital to look for the cause of the disease in the pharynx or trachea and treat the problem. Parents are advised to avoid smoking in an environment with children, keep the air circulating, avoid allergenic substances in the home, and usually pay attention to giving the child more water and taking the baby outdoors in the sun to strengthen the child’s immune system.
