- Changes in Boys. Boys tend to show the first physical changes of puberty between the ages of 10 and 16. The growth spurt of boys is, on average, about 2 years later than that of girls. By age 16, most boys have stopped growing, but their muscles will continue to develop.
- Feet usually stop growing a few years after puberty. In girls, the “normal” age for feet to stop growing is around 14 years, while in boys, it's around 16. However the final closure of growth plates in the feet occurs between 18 and 20 years of age.
- Size six is the new four (for women), and size 10 the new eight (for men). Our feet are getting bigger, increasing by an average of two sizes over the past four decades, according to the College of Podiatry. Once, a size 14 shoe marked a man out as a giant.
The average 11-year-old boy would be around 55 inches tall and weigh around 80 pounds. When your doctor shows you how you plot on the growth chart, you'll notice that you are quite a bit below the average in height and quite a bit above the average in weight.

- For about a decade, the paediatric sleep community has recommended that children three to five years old need 11 to 13 hours, children five to 10 years old need 10 to 11 hours, and adolescents 10 to 17 years need eight-and-a-half to nine-and-a-half hours of sleep each night.
