What is normal growth?
Growth is increase in the size of the body or quantitative growth (includes height and weight). Other components of growth include brain growth (head circumference) and nutritional status (mid-arm circumference). Growth also goes hand in hand with development (see Is my child’s development on track?)
Growth in the first year of life is remarkable. The baby grows 10 inches (25cm) on average, and its birth weight triples. After this the growth slows a bit. After the age of 2, your child will grow about 2.5 inches (6cm) a year till adolescence, but this is variable. There may be times of slow growth, followed by growth spurts.
