What’s wrong with babies shaking their heads and scratching their ears a lot? Is it a disease? Do I need treatment? Some children often shake their heads or even bang their heads and sometimes sway their bodies, which is as normal as a child’s tendency to jump and hold. The vestibular system of the child needs to seek stimulation, the vestibule is the maintenance of balance organs, most infants will have a vestibular “self-stimulation” stage, will make up and down jump, shaking the head and shaking body movements. Between 3% and 15% of infants will also bang their heads against other objects. Vestibular self-stimulation usually begins between 6 and 8 months of age, when vestibular sensitivity is at its peak. This behavior can disappear in a short period of time or last for a longer period of time, with most disappearing by 1 to 1.5 years of age. Intellectual development is cumulative, and the vestibular system is one of the first senses to develop, accounting for much of an infant’s early sensory experience, which may have a critical role in unity and other sensory and motor aspects, and so also affects higher-level emotional development and cognitive abilities. Some babies like to pick at their ears with their hands. Checking the child’s outer ear area, no abnormalities are seen. This is because the inner ears of both ears are unevenly developed, the balance receptors are not well developed, and the baby feels uncomfortable with his ears, so he likes to pick at his ears with his hands, which does not need to be treated and will disappear naturally after a few months.
