Baby intellectual disability mainly refers to a situation where a baby's intellectual development is lower than normal. When a baby reaches the age of eighteen, their intellectual development still shows a relatively low level, resulting in permanent intellectual disability. Intellectual disability is not a disease, but a physiological defect. So, the manifestation of intellectual disability in a one-and-a-half-year-old baby?
1. Walking obstacles. At the age of one and a half years, most babies have already learned to walk. Intellectually disabled babies tend to be slow in walking, with clumsy feet that cannot coordinate well. Their bodies lack sufficient coordination and cannot take steps on their own, resulting in poor balance.
2. Language barrier. A normal baby can imitate an adult's tone and learn to speak at eight months old. By one and a half years old, they can speak simple words fluently and express themselves. Babies with intellectual disabilities tend to be quieter, unable to learn to speak, lack awareness of speaking, or exhibit clumsy mouth movements and sounds when speaking.
3. Abnormal facial appearance. Intellectually disabled babies have significant differences in their facial appearance. The distance between the eyes of intellectually disabled babies is too large, the outer corners of the eyes are raised, the nose bridge is collapsed, the tongue is often swallowed or hung at the corners of the mouth, drooling, etc. At the same time, there are many facial expressions, such as winking and smiling, and often humming.
