Other colleagues in the hospital often ask me why I work hard every day to popularize science, and I often laugh at it when I have this time.
It's because I've met too many parents who tell me that they regret not getting in touch with this knowledge earlier, which causes the regret of their children's height.
Therefore, I hope to use a simple, understandable way of popular science that parents can understand, so that everyone can understand growth and development.
Adolescence is the last golden period for a child to grow, and it also means that the child will enter the countdown, puberty will end, the epiphyseal line will be closed, and the child's height will be fixed.
If you want your child to be taller and more ideal, when will puberty start, what is the order of development, and when will it end, we parents must know that boys and girls are different.
When does a child start puberty?
Boys generally begin puberty at about 11 and a half years of bone age, and the signals of initiation are relatively insidious, starting from the lower body and starting from the testicles and penis.
Parents can take out the bone age film of the left hand, and when the epiphysis of the middle phalanx is equal to one or both sides of the backbone, it means that the child has entered a period of rapid growth and is about to start to run.
Girls generally begin to reach puberty around the age of 9 and a half years of bone age, and the signals of initiation are easy to detect and begin to develop from the breast of the chest.
When the sesamoid bone under the thumb appears, it means that the girl will have her period in about a year, and generally it will not grow much after menstruation.
How do you make sure your child grows more than average?
When a boy enters puberty, he is more than 150 tall, and he is more than 172 in adulthood;
When a girl enters puberty, she is more than 135 tall, and there is a high probability that she will grow more than 160 in adulthood.
When does the child end growing up?
Bone age determines how much more a child can grow and how long it can grow, with boys stopping growth at about 16 years and girls at about 14 years old.
Boys have a long Adam's apple, which is a sign of entering the middle and late puberty, and most children have an Adam's apple at about 14 to 14 and a half years old, and the child's growth space is generally 7-8 cm at this time.
Menstruation in girls is a sign of entering the middle and late stages of puberty, and most children menstruate at about 12 and a half years old, with a growth space of about 5-6 cm.
If the epiphyseal line is closed, and everyone comes back to me for a solution, I can only say sorry.
