The main symptoms of bronchitis in children are coughing and excessive phlegm, and there may also be symptoms such as fever, vomiting, and diarrhea. Generally, when caring for a sick child at home, it’s important to pay attention to their diet. The diet should be light and easy to digest, with an appropriate increase in nutrition. Foods that are too sweet, too salty, or cold should be avoided. Also, avoid giving the child big tonic foods or foods that are rich and greasy, like fish, shrimp, or crab, which can cause allergies. Additionally, ensure the air has adequate humidity, typically maintaining it between 55%-65%. Let the child drink warm water frequently, change positions regularly, and pat their back to help expel phlegm. Proper rest is also important. If the child is really uncomfortable, has persistent coughing, or shows clear signs of fever and irritability, it is advised to go to the hospital promptly, so a doctor can assess the child’s condition and treat them accordingly.
