What Are the Symptoms of Poor Infant Nervous System Development?

When the development of an infant's nervous system is not optimal, their developmental milestones may be delayed, and they may be unable to lift their heads, smile spontaneously, or engage in other activities at appropriate ages. Parents should be vigilant about any signs of abnormal neurological development in their infants and promptly take them to the hospital for examination. If necessary, they may require treatment with trace elements and rehabilitation training.

1. At 1 month, the infant cannot follow moving objects with their eyes; at 2 months, they do not respond to being teased and cannot produce vowel sounds such as "a," "o," or "e"; at 3 months, they cannot laugh out loud or smile spontaneously when seeing people; at 4 months, they cannot recognize familiar faces, cannot shout loudly, and cannot hold their heads up 90 degrees when lying on their stomachs.

2. At 6 months, the infant does not understand their own name; at 7 months, they still cannot sit unsupported; at 8 months, they cannot imitate sounds; at 9 months, they cannot crawl or express greetings or farewells; at 1 year, they cannot call "dad" or "mom."

1. Delays in development simply mean that the infant is lagging behind the average level of their peers. However, some infants may only be temporarily slower and catch up later, while others may have intellectual disabilities. Close observation is necessary.

2. There are many trace elements involved, with the most common being zinc, iron, copper, and magnesium. Treatment should focus on replenishing the specific trace elements that the infant is lacking.

3. By 3 months, infants should be able to lift their heads and smile, although some may not yet be able to laugh out loud. They should respond to sounds, but their sensitivity to the direction of sound may not be fully developed.
