It is very normal for babies to shake their heads, but if they keep shaking their heads it can be caused by a variety of factors. For example, poor body balance, skin diseases, itchy ears, calcium deficiency, neurological disorders and many other factors can cause. The first thing to do is to observe the duration of the shaking of the baby’s head, and if the symptoms are recent, check the baby’s skin and ears for any disease or inflammation. If the skin has inflammation such as dermatitis, eczema, etc., the itching is too strong will stimulate the baby to make head shaking behavior. And to look at the ear, if there is ear wax inside the ear to stimulate the ear itching will also appear to shake the head. Because the baby’s body functions are not fully developed, so the balance ability is relatively poor, so some babies will often appear left and right head shaking phenomenon. In addition, some children may have vitamin D deficiency or the environment is not the right temperature, resulting in excessive sweating, the child may be due to localized itching caused by head shaking. Neurological disorders, such as epilepsy, can cause babies to shake their heads erratically and with convulsions. Therefore, if the baby always shakes his head, it is best to take him to the hospital for relevant examinations, clinical pediatricians will be based on the baby’s various symptoms to determine whether it is physiological head shaking or pathological head shaking.
