Failure to thrive (FTT), also known as weight faltering or faltering growth, indicates insufficient weight gain or absence of appropriate physical growth in children. [ 2 ] [ 3 ] FTT is usually defined in terms of weight, and can be evaluated either by a low weight for the child's age, or by a low rate of increase in the weight.
Intrauterine growth restriction (IUGR), or fetal growth restriction, is the poor growth of a fetus while in the womb during pregnancy.IUGR is defined by clinical features of malnutrition and evidence of reduced growth regardless of an infant's birth weight percentile. [5]
Stunted growth, also known as stunting or linear growth failure, is defined as impaired growth and development manifested by low height-for-age.

[ 6 ] A related term is low birth weight , defined as an infant with a birth weight (that is, mass at the time of birth [ 7 ] ) of less than 2,500 g (5 lb 8 oz), regardless of gestational age at the ...
Young toddlers (12 months) have a wider midfoot than older toddlers (24 months). The foot will develop greater contact area during walking. Maximum force of the foot will increase. Peak pressure of the foot increases. Force-time integral increases in all except the midfoot. The lateral toes did not show a pattern in development of walking.
Charts based on a specific race or ethnicity are not useful because of the growth chart progression can be attributed to socioeconomic factors. [14] WHO launched a revised growth in 2006 chart using children from Ghana, Oman, Norway, Brazil, India and the USA that substantiated the fact that growth is highly dependent on environmental factors.

The mean pregnancy length has been estimated to be 283.4 days of gestational age as timed from the first day of the last menstrual period and 280.6 days when retrospectively estimated by obstetric ultrasound measurement of the fetal biparietal diameter (BPD) in the second trimester. [12]
