All children grow at different rates. Growth rates depend on many individual aspects of a child ‘s liveliness including both genetic and environmental factors. To help determine whether a child is growing at an average rate in both altitude and burden, pediatricians refer to increase charts that graph a range of heights and weights for children at a particular senesce. This data informs the baby doctor how a child compares to other kids her age .
Home On the Range
Using growth charts, it is easy to see that the normal altitude and weight ranges for 3-year-old girls and boys are exchangeable. Girls range from 35 to 40 inches in height, and boys are on average a one-half inch grandiloquent. Girls have a slant crop of 25.5 to 38.5 pounds and boys range from 27 to 38.5 pounds.

BMI is a calculation that incorporates both a child ‘s acme and weight into one measurement. According to the Centers for Disease Control ‘s measurements for the year 2000, the normal BMI crop for a three-year-old girl is 14 to 18.2, and for boys the range is 14.4 to 18.2 .
