Whether an infant’s intelligence is normal or not is usually assessed by a medical professional at a regular hospital. In daily life, it can be observed through the appearance, behavior, language, etc., but the specifics need to consult a physician.
1. Appearance: If there is developmental delay, there will be expression of stupidity, and babies over eight months old still drool.
2. Behavior: Slow movement, poor reaction time, lack of concentration when doing things, and cognitive impairment indicate abnormal development.
3. Language: slurred speech, speaking much later than normal infants, etc. also indicate abnormal intellectual development.
There are many factors affecting the intellectual development of infants, such as: severe prenatal complications in the mother, difficult labor, premature birth, umbilical cord wrapping during delivery, placental abruption, etc., all of which will have an impact on intellectual development.
Specific assessment should be done in a regular medical institution.
