The vestibule of the infant’s inner ear begins to function at 8 to 9 months of gestation, peaks at 6 to 12 months, and reaches adult levels at 10 to 14 years of age. The vestibular system begins to develop very early in fetal life, with the vestibular apparatus morphology completing on day 49 of gestation, and the fetal vestibular system is ready to begin functioning by 8 to 9 months of gestation. After birth, the vestibular system continues to develop and mature, reaching its peak of sensitivity between six months and one year of life, and this change contributes to the development of balance and motor control. As the child continues to develop, the sensitivity of the vestibular response decreases due to central inhibition and cerebellar modulation, and reaches adult maturity between the ages of 10 and 14. Vestibular function is involved in the regulation of whole body gross motor development such as rolling over, postural reflexes, head stabilizing movements, and visual stabilization in children. If there are any signs of delayed or abnormal gross motor development, or postural control abnormalities, it is recommended to go to the hospital in time for consultation.
