If a girl shows signs of secondary sexual characteristics before the age of 8 or a boy starts sexual development before the age of 10, it may be a sign of precocious puberty. Generally, hospitalization is not required. As a parent, you should pay attention to your child’s diet and avoid feeding them high-calorie and hormone-rich foods. If your child is already 16 years old, this may no longer fall under the category of precocious puberty.
