Puberty is when a child’s body begins to develop and change as they become an adult. Girls develop breasts and start their periods, and boys develop a deeper voice and start to look like men.
The average age for girls to begin puberty is 11, while for boys the average age is 12. But there’s no set timetable, so don’t worry if your child reaches puberty before or after their friends. It’s completely normal for puberty to begin at any point from the ages of 8 to 14. The process takes about four years overall.
