The height of a baby varies in range depending on the gender. The average height of a one-year-old female baby is around 75.0cm. When the height is less than 69.7cm, it will be considered as growth retardation. One year old male babies are considered to be stunted when their height is less than 71.2cm, with an average height of about 76.5cm. If the baby’s height growth is not satisfactory, first of all, you need to exclude special diseases, such as hereditary, congenital metabolic diseases, or special diseases after birth, such as short-term acute infections, pneumonia, etc. These diseases affect the baby’s overall nutritional intake, which affects the growth of length and weight. If, in addition to congenital hereditary diseases, there are no obvious, acute infections and other diseases that affect the baby’s appetite, and there is unsatisfactory height growth, the first thing to consider is that the overall feeding may be inadequate and the energy intake is insufficient, and the short-term effect is unsatisfactory weight growth. When this situation persists, it will eventually affect the growth of height, so when the height growth is unsatisfactory, you need to ask your doctor to judge it, according to the trend of the growth curve, to analyze the possible causes, and then give symptomatic guidance to gradually catch up with normal children.
