As I grow

Puberty is the time when your body changes from a child's to an adult's. Puberty happens to girls and boys between the ages of eight to 16 years and is nothing to worry about.

What is it?

Our brains release hormones that tell the body it is time to start changing. This happens over a few years, not overnight, so you may not even notice the changes happening!


Some changes are the same for boys and girls:

  • Growing taller.
  • Hair in ‘funny places’ – under your arms and between your legs
  • Sweating more. Yes, that means a wash, shower or bath every day!
  • Greasier skin. You might even get a few spots – do not squeeze these as it makes them worse. Just remember to have a wash every day.
  • Greasier hair. You may start to notice that you will need to wash your hair more often.
  • Mixed up feelings and mood changes‚Ķ happy, sad, grumpy, tearful, angry, fed up, confused, excited. These are all normal feelings – it is just your ‘puberty brain’ getting used to a brand new you!
  • Feeling differently towards others. You might start to ‘fancy’ people.
