What are the symptoms of intellectual disability in a 2-year-old baby?

Generally speaking, when babies reach the age of two, they are more active, learn to walk, and sometimes talk. But in real life, some two-year-old babies still don’t know these things. Judging from their various behaviors, they are still different from other babies. Some people say that such babies may have low intelligence, so what are the manifestations of low intelligence in 2-year-old babies?

1. Abnormal facial and body shape:

Symptoms include wide-set eyes, slanted eyes, collapsed nose, tongue hanging out of the mouth, drooling, etc. It is what people often call "face". Children with hydrocephalus have particularly large head circumference, while children with microcephaly have particularly small heads. People with hypothyroidism are particularly short, people with phenylketonuria have abnormally white skin and very light hair, etc.

2. Motor development retardation:

He learns to lie down, raise his head, sit, stand and walk later than children of the same age. In particular, it will manifest as late walking, often after the age of 4, the child will be able to walk independently, and his or her walking is unstable.

3. Language development is delayed:

Generally speaking, children will be able to imitate sounds at 7-8 months old, begin to consciously call mom and dad at around one year old, and after one and a half years old, they will be able to say commonly heard words and understand simple conversations. They can answer simple questions at around 2 years old and express their own thoughts at 2 and a half years old. If a child lags behind normal children by 5 months or even 1 or 2 years, parents should take it seriously and consider whether the child has intellectual disability.

4. Hyperactivity:

In contrast to children who are too quiet, hyperactivity is also a characteristic of some intellectually retarded children. Many mentally retarded children cannot stay still for a while and are active all the time. This is especially evident in children aged 4-5 years old.

5. Lack of concentration:

Intellectually retarded children have difficulty concentrating. Their attention span is significantly shorter than that of normal children. Even when they are 5-6 years old, they can only concentrate on one thing for no more than 5-6 minutes. They also pay little attention to the outside world.
