In general, when a baby is cold, eats milk too fast, or inhales cold air during the process of eating milk, the autonomic nerves are stimulated, causing the diaphragm to suddenly contract, resulting in the phenomenon of hiccups. The hiccups can be relieved by patting the baby’s back, massaging it properly, drinking water properly, or by inhibiting exhalation. 1. pat the back: parents can hold the baby vertically, let the baby’s head rest on their shoulder, and gently pat the back from the bottom up with a hollow hand. most babies can be relieved of hiccups sooner. 2. massage properly: massage properly by sticking the soft end of a cotton swab into the mouth. Gently massage the midline of the soft palate for about 1 minute to effectively control hiccups. But pay attention to the operation, must be particularly careful to avoid damage to the oral cavity. You can also massage your abdomen clockwise to relieve hiccup symptoms; 3. Drink water appropriately: If the hiccups are caused by cold, you can drink some warm water appropriately and then let your body bend slightly so that your stomach and diaphragm are relatively close to each other. After warming to the diaphragm, it will relieve the diaphragm spasm and also achieve the effect of stopping hiccups, while avoiding getting cold; 4. Inhibit exhalation: Cover the mouth and nose with a small sealed bag when the child exhales. This is because after repeated inhalation of exhaled carbon dioxide, the concentration of carbon dioxide in the blood will increase and will also stop the hiccups. However, care must be taken that this is done properly to avoid hypoxia. If the hiccups are not relieved by the above methods, there may be some disease problems, so you should go to the hospital for relevant examinations and actively give symptomatic treatment after a clear diagnosis in order to relieve your baby’s hiccups.
