Is it normal for a 9-month-old baby to still be unable to stand steadily?

A 9-month-old infant who is still unsteady on their feet may be affected by physiological factors, or possibly pathological factors such as calcium deficiency or developmental delay. A detailed analysis is as follows:

I. Physiological Factors

If the baby is excessively overweight or heavy, they may be unsteady when standing. Additionally, poor balance ability in infants can also lead to instability while standing. These are considered normal physiological factors that do not require treatment—regular, appropriate physical exercise is usually sufficient.

II. Pathological Factors

1. Calcium Deficiency

This may result from low immunity or insufficient dietary calcium intake. When the body lacks adequate calcium, it may lead to weakened bones and consequently cause instability when standing. It is recommended to increase consumption of calcium-rich foods, get more sun exposure to enhance calcium absorption, and, under medical guidance, take oral supplements such as lysine calcium phosphate granules, calcium gluconate oral solution, or calcium carbonate D3.

2. Developmental Delay

Insufficient nutrition or abnormal hormone levels may lead to delayed development, which could explain why a 9-month-old baby cannot stand. Under a doctor's supervision, medications such as Pediatric Intelligence Syrup or oral cerebroprotein hydrolysate may be used. In addition, rehabilitation training should be implemented.

Besides the above causes, conditions such as rickets may also contribute. It is important to seek prompt evaluation at a正规 hospital to determine the underlying cause and receive appropriate treatment.
