No, as the definition of growth is a change in body size over a period of time. Therefore, some other form of assessment of growth is needed when you cannot wait a few weeks or months to decide whether the child is growing normally or not. An assessment of growth can be made if the size of a child is compared to the size of other children of the same age. In order to do this, the normal (i.e. average size) range of children of that age is needed. If the child’s size is the same as most other children of the same age, then the child is probably growing normally. The most commonly used growth charts are centile charts.
