Question
What measures should be taken if a nine-month-old baby has poor brain development?
Answer
According to your description, following the normal developmental trend, the average height of male infants may be slightly higher than that of female infants. According to children’s growth standards, the standard height range for newborn male infants is 45.2-55.8 centimeters, with an average of 50.4 centimeters; for female infants, it is 44.7-55.0 centimeters, with an average of 49.7 centimeters. As the child grows older, influenced by factors such as nutrition, genetics, and environment, there will be certain differences in height. In the process of the child’s growth, it is recommended to refer to the corresponding standard scales.
