By this age, infants may have doubled their birth weights. They typically grow about 0.8 inches (2.0 cm) and gain about 1 to 1.5 pounds (450 to 680 g) during this month. [28] Fat rolls ("Baby Fat") begin to appear on thighs, upper arms and neck. Motor development. May be able to roll from front to back. [29] Starts to reach and grasp for ...

Stunted growth, also known as stunting or linear growth failure, is defined as impaired growth and development manifested by low height-for-age. [1] It is often caused by malnutrition and can occur due to endogenous factors (such as chronic food insecurity ) or exogenous factors (such as parasitic infection ).
Growth then proceeds at a slow rate until a period of rapid growth occurs shortly before puberty (between about 9 and 15 years of age). [86] Growth is not uniform in rate and timing across all parts of the body. At birth, head size is already relatively near that of an adult, but the lower parts of the body are much smaller than adult size.
Maximal adult height is achieved at an average age of 15 years for an average female and 18 years for an average male. Potential fertility (sometimes termed nubility) usually precedes completion of growth by 1–2 years in females and 3–4 years in males. Stage 5 typically represents maximal gonadal growth and adult hormone levels. [citation ...
Although physical growth is a highly regular process, all children differ tremendously in the timing of their growth spurts. [69] Studies are being done to analyze how the differences in these timings affect and are related to other variables of developmental psychology such as information processing speed.
Adult height is usually in the normal range, although Broc Brown has the condition and was named the world's tallest teenager; as of late 2016, he was 2.34 m (7 ft 8 in) tall and still growing. [ 2 ] Individuals with Sotos syndrome often have intellectual impairment, [ 3 ] [ 4 ] and most also display autistic traits. [ 5 ]
Growth charts are different for boys and girls, due in part to pubertal differences and disparity in final adult height. In addition, children born prematurely and children with chromosomal abnormalities such as Down syndrome and Turner syndrome follow distinct growth curves which deviate significantly from children without these conditions.
