Your Son at 10: Milestones

At age 10, your son is growing steadily. He’s starting to solve problems logically and is likely to be more independent.

Your Son’s Body

Your son is likely to stand somewhere between 4 and 5 feet tall at this age. His weight should be between 65 to 90 pounds. He could grow up to 4 inches a year, but about 2 inches is normal until he starts puberty.

He’ll be getting stronger, with his balance, stamina, and coordination improving. His ability to play team sports gets better. He should be able to use some tools, and his ability to do detailed activities like painting may be increasing.

He’ll have lot of energy and should be getting at least an hour of physical activity a day. His diet should be high in fruit and vegetables and lower in fats, added sugar, and salt.

Time spent watching television or playing with electronic devices should be limited to 2 hours a day or less.

Some of your son’s permanent teeth, particularly the ones closer to the back, are still coming in at this age.

Your Son’s Brain

At age 10, your son’s brain continues to develop. His schoolwork may be uneven at this point, and his interests may be changing rapidly. But his attention span is increasing, and judgement is improving. 

He’s most likely skilled at reading and writing, and can speak clearly. He’s developing abstract and critical-thinking skills, can follow detailed directions, make plans, and reason through problems.

He should be able to read and understand books that are more challenging and mathematical problems, including fractions, word problems, and multiplication and division involving long numbers.

His curiosity is likely growing, and he might ask a lot of questions about the world around him. He may start to show more creativity in things like writing, designing, or performing arts. He might also start to develop hobbies or collect things.

By this age, he should understand how his behavior affects others. He also should recognize and consider other people’s opinions and views and have a sense of what’s right and wrong, fair or unfair.

Your Son’s Relationships

At 10, your son likely is still closely attached to you. But he’ll start to build stronger ties with friends and classmates, and group identification and peer pressure are growing at this age.

Most of his friendships will be with other boys, but he may have more interest in girls. Friendships are largely based on common interests. Loyalties to teams, clubs, or other groups are strong. Things like sports and board games will become more common than fantasy play at this age.

As he becomes more skilled physically, he’s likely to become more competitive. Conflicts with siblings may happen more often.

With puberty around the corner, he may have more mood swings. He may be more sensitive or get discouraged easily, or become more self-conscious about his body.

He’ll still tend to see adults as authority figures, follow their rules, and accept the beliefs of your family. But he’s likely to question authority, see older kids as role models and become more conscious of what others think of him.   

Checklist

At your son’s annual medical checkup, your doctor should examine:

  • His height and weight
  • His vision and hearing
  • His physical development and behavior
  • His immunization records, making sure he’s current on vaccinations

In addition, your doctor will ask some questions to assess your son’s risk of conditions that may develop later in life, such as tuberculosis, high blood cholesterol, and anemia.
