Height and weight percentiles became very important in my house after my son was born. Our pediatrician checked them every appointment, my friends and family often asked his percentile and I recorded every percentile change in his baby book. Growth charts compare a child’s height and weight to the national average for each age and gender. These national averages form a curved line, which is the 50th percentile curve. Theoretically, 50% of children are above the curve and 50% are below. Following the chart tracks any unusual changes in the child’s growth.
