There are many signs of puberty in girls. Keep in mind that these stages may appear gradually and it may take three to four years for your child to cycle through all the phases of puberty. In general, boys will go through puberty at some point between the ages of 9 and 14. Girls may begin between the ages of 8 and 12. Share these signs with your tween daughter so she knows what to expect.
