Puberty is something that everybody goes through ranging from the age of 8 to 17 for girls, and 9 and 14 for boys. However some people can go through puberty earlier or later, which is fine and everybody is different. Puberty is where your body grows in different ways and types such as height, weight, voice getting deeper, periods, hair in places like your genitals, and you can also grow emotionally, getting mood swings, getting crushes, changing friend groups, and getting more distant from parents.
