Girls
In general, a girl's growth spurt starts when she's about 9. It ends within a year of her first period, which is now at a national average of 12 1/2 years old. Her breasts are growing from the "bud" stage of the preteen years.

Girls ages should eat about 2,400 calories a day.

Boys
In general, a boy's growth spurt starts when he's about 13. He can be chubby before he starts to grow taller, and then he can seem too thin. Hair is now visible in armpits, on legs and arms, and a slight mustache will form. His sweat glands are changing, and he will probably want to start wearing deodorant.

I was taller than most boys in sixth grade; however, when we came back to school when were seven graders, they were all taller then me.

A big change happened to me this summer. I had my tonsils taken out the first part of the year.
