Characteristics of boys beginning to develop

Human growth and development is a long, varied and complex process. There are many changes from infancy to adolescence. Boys generally gain weight and grow taller from childhood to adolescence. There are also some changes inside the body, such as the growth of pubic hair and armpit hair, and the voice becomes thicker and deeper. So what are the characteristics of boys' development?

1. Children are usually fat before the age of two, and gradually become thinner after the age of 3-4. In pediatric clinics, we often see parents bring their 3-4 or 5-6 year old children to the doctor for a comprehensive examination, complaining of being "thin". There are many reasons why children do not gain weight, in addition to factors such as constitution, nutrition, diet, sleep, illness, exercise, genetics, etc., children of this age are generally thinner than when they were young.

Because the physical development of children at this age is much slower than that of infants and toddlers, children aged 3 to 6 years old grow in height on average each year, while their weight only increases by 1.5 to 2 kilograms per year. In addition, the brain function of children at this age is becoming more and more complete, and their activity level is increasing. Apart from eating and sleeping, they have almost no free time, so the body's calorie consumption increases relatively, so the body begins to become thinner and the subcutaneous fat decreases.

2. What are the characteristics of boys' development?

To know whether the child's growth and development is normal, you can judge from the child's height, weight, chest circumference, head circumference, etc. Weight reflects the child's nutritional status. If the child's weight is more or less than the standard by 10%, it can be considered normal. If it is more than 15% below the standard weight, it should generally be considered as underweight, which may be caused by malnutrition or some chronic wasting diseases.

Children's situations are different, and their growth is different. Both boys and girls have their own differences, so parents don't need to worry too much. Children's growth has standards, as long as it is within the normal value, everyone does not need to worry too much. If there is an abnormality, you should pay attention to the cause and ensure the health of the child, so parents don't need to worry.
