Coughing and dry heaving in babies may be caused by improper feeding, irritation of food, allergy and other factors. It needs to be handled in conjunction with the different conditions of the baby, such as burping the baby, removing allergens and giving appropriate medication. 1. Improper feeding: When babies drink milk, they suck in too much air, which may lead to coughing and dry heaving. It is recommended that after each feeding, babies should be held upright and gently burped to knock the air out of their stomachs, which can reduce the occurrence of the above symptoms. 2. Food stimulation: If you don’t pay attention to your eating habits and consume stimulating food, it can cause your baby to cough and dry-heave. It is recommended to take warm water in moderation to reduce irritation. 3. Allergy: babies with allergies, when stimulated by pollen, dust mites, food, etc., cause allergic cough and dry heaving. It is recommended to detach from the allergens and give loratadine (caution for less than 2 years old) if necessary to relieve the symptoms. In addition, inflammation of the mucous membrane of the throat can also cause the above symptoms, it is recommended to go to the pediatric internal medicine department of the hospital in a timely manner, combined with the doctor’s advice to give the appropriate drug treatment.
