Two-year-old baby mentally retarded

Babies cannot express themselves when they are just born, but they will gradually learn some social behaviors as they grow older. Many diseases of the human body manifest themselves in childhood, and mental retardation is one of them. Parents dare not imagine that their baby may be mentally retarded, because if so, it will affect the baby's life. So what are the symptoms of mental retardation for a two-year-old baby?

Appears in infancy. The earliest symptoms shown by infants with mental retardation are often difficulty in feeding, inability to suck, and being particularly prone to spitting up milk, which indicates damage to the nervous system and will affect their intelligence in the future.

2. Abnormal facial and body shape

Some babies with congenital mental retardation have abnormal facial and body appearance. For example, children with congenital idiocy have symptoms such as wide-set eyes, slanted eyes, and collapsed noses. 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.

3. Motor development retardation

Babies with intellectual disabilities have significantly slower motor development than normal babies. The starting age for movements such as raising the head while lying on the stomach, sitting, standing, and walking is later than that of normal children of the same age. This is especially obvious in walking. It is often not until the age of 3-4 or 4-5 that the child can walk independently, and the walking is unstable.

4. Language development is delayed

Normal babies will imitate sounds at 7-8 months old, call mom and dad at around one year old, can say a dozen words at one and a half years old and understand simple instructions, can ask simple questions at around 2 years old, and can basically express their thoughts at around 3 years old. If these symptoms appear only after a child is four to five months behind or even one to two years behind, they should be regarded as a sign of intellectual disability.

Mentally retarded babies are indifferent to their environment. In the first 1-2 months after birth, the baby will not make eye contact with adults and will not smile when teased. He is very quiet all day and rarely cries. The intellectual problems of these babies are generally easily overlooked.

6. Hyperactivity

In contrast to babies who are too quiet, hyperactivity is also a characteristic of some intellectually retarded babies. Many mentally retarded babies cannot stay still for a while and are active all the time. This hyperactivity is different from the liveliness and mischief of normal children. They have no purpose but just an irrepressible excitement. They touch everything they come across and don't even know how to pick up chairs and stools if they knock them over.

Intellectually retarded babies have difficulty concentrating. Their attention span is significantly shorter than that of normal babies. 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.

8. Visual and hearing impairment

Severe visual and auditory defects, such as severe myopia, hyperopia, astigmatism, total deafness, and hearing loss, also have a great impact on intelligence. Because vision and hearing are the means of communication between people and the outside world, they will lead to intellectual development delay.
