Monitoring of height, weight, and head circumference provides a good indication of the baby's health and vitality during the first year. Often, the growth of a child with health or eating disorders is slowed down.
At each consultation, the doctor measures and weighs the baby. The results are then plotted on the indicative curves in the health record. These curves make it possible to check if the child is in average, materialized often by a colored zone. However, do not worry if the child is not exactly in this average type; each baby's growth rate. The most important is the regularity of the curve, that is, its progression. For example, a stagnant weight, a diminishing weight, or a sudden slowing down of the size curve is not normal.
If there is a problem, the doctor will analyze other possible symptoms. Thus, he will practice a detailed neurological examination, and will be interested in the psycho-emotional development of the child.
The size curve
Babies are measured in a supine position on a special height.
The measurement of the waist is plotted on the curves of the child's health record. We analyze the deviation from the mean value, in standard derivation (DS). When the difference is greater than 2 DS, usually the doctor performs some investigations.
As an indication, a baby will take on average 3 cm per month up to 3 months, then 2 cm per month up to 6 months. From 6 months to 1 year, it will take on average 1 cm to 1.5 cm per month. At birth, it measures on average 50 cm, and about 75 cm at the age of one year.
In the case of stunting in a child, some factors are taken into account, such as height at birth, or height of parents (heredity is often a small factor). If the difference is large between the size of the child and the standard, additional tests may be performed, such as X-rays to assess bone age.
