I am a 12- year-old male secondary school student. My problem is that my 11- year- old younger sister is taller than me. I want to know if I will still be tall because I am not happy that my younger sister is taller than me.

Puberty is when a child’s body begins to develop and change as they become an adult. Since the average age for girls to begin puberty is 11 years, and for boys 12 years, you may still be taller than your younger sister. However, if she still becomes taller than you, you have nothing to worry about since she is still your sister.
