The growth spurt is one of the first signs of puberty. A girl may grow as much as four inches taller in a single year. After this, growth slows down considerably. Most girls completely stop growing about one to three years after the first period, while some gain an inch or so up to the age of 21. A girl s feet grow at a fast pace, reaching their full adult size much before the rest of the body.
Pubic hair begins to grow in a triangular patch in the pubic area, lightly at first.
This is followed by hair growth under the arms. Hair on the legs and sometimes hair on the arms begins to darken. Some girls are worried by excessive hair on their limbs and upper lip and may request cosmetic attention. The genitals, which are not conspicuous in a child, grow and become more evident during puberty. The female external genitals include the vulva, labia and clitoris.
