Many babies shake their heads, although the reasons for this vary, so mothers need to observe whether their babies have other characteristics that can help explain why they shake their heads. Some babies like to shake their heads may simply be a physiological phenomenon and nothing special. Infancy is the time when babies’ brains are developing the fastest, when their eyes and ears begin to gather all kinds of information, experience their relationship with their environment, feel and master their bodies, and it can be seen that when babies are not yet capable of making their limbs move fully, forcefully and purposefully, they are already able to shake their heads as they see fit. So, it is possible that the experience is being repeated over and over again. Of course, when babies shake their heads, they have to think about whether they are uncomfortable, for example, itching of the head or itching of the ears caused by eczema in the external ear canal may make them try to relieve the itching by shaking their heads helplessly. So, when your baby shakes his head, you need to pay attention to these problems. Calcium-deficient babies may have sleep disturbances and irritability, but they can’t express it as fully as we adults can, standing up and spinning around twice or trying to think of something else, or they can only shake their heads in annoyance. Therefore, shaking the head does not necessarily mean that there is a problem again, but it is still necessary for us adults to fully observe, and if we are not sure, we need to go to the hospital to find out the cause together with the doctor.
