In recent years, the onset of puberty in children worldwide has been advancing. For girls around the age of ten, development is generally normal. Families should maintain a calm attitude, pay attention to the rational selection of food, and at the same time, consider conducting a comprehensive check-up for the child. Take measures to inhibit or slow down the development of secondary sexual characteristics as much as possible to improve the final height in adulthood and restore the appropriate psychological behavior for their age. Pay attention to regular checks for leukorrhea; if there is an infection, timely antibiotic treatment should be administered.
