Early puberty is when a child's body begins changing into that of an adult (puberty) too soon.
Precocious puberty refers to puberty that starts earlier than normal (before age 8 for girls and before age 9 for boys). This takes the form of early development of signs of puberty. The cause is unknown, but could be due to hormonal imbalances, genetic conditions, central nervous system problems or a positive family history.
