Child Physical Developments

A 15-year-old is not a child anymore, yet not an adult either. It is a crucial year in helping your child move towards becoming a mature adult. Your child, however, may think otherwise. He is probably already turning rebellious with a know-it-all attitude. 

Here’s what to expect in terms of their physical development.


  • Larger penis and testicles that start to make sperm

  • Pubic hair, then underarm and facial hair

  • A deeper voice that sometimes cracks

  • Bigger Adam’s apple Eat a lot and are almost always hungry

  • Get taller and more muscular

  • Need lots of sleep

  • Can be clumsy because they’re growing


  • Developed breasts 

  • Have pubic hair

  • Reached their adult height

  • Had their first menstrual period.

  • Many of them are insecure about their appearance, especially their weight.
    Nearly half of all high school girls diet to lose weight.

This is the right time to teach your child that with independence comes responsibility. Getting them to earn their freedom by handling independence like responsible adults is a good idea. Familiarize yourself with the signs and symptoms of eating disorders and other mental health problems. If you suspect your child has an eating disorder, body image issues, or mental illness, seek professional help.
