What is the standard weight for male baby children?
The average weight of a newborn baby is 3.25kg. As the child grows older, both weight and height will change, but attention should also be paid to the rate of growth in height and weight. If it is lower than peers, further examination is needed to determine if there is any developmental abnormality. Furthermore, the growth and development of a child's height and weight are also related to their genetic factors.
1. Weight Standards for Boys at Different Ages
There is not much difference in the growth of weight and height between boys and girls when they are just born. The average weight of a newborn baby is generally 3.25kg. In the first month after birth, the weight gain of a normal full-term newborn can reach 1-1.5kg. By 3-4 months, the weight can double to about 6-6.5kg. By one year, the weight can reach 9-10kg, and from 2 to 12 years, the weight increases approximately 2-3kg per year. For children aged 2-6, the general weight formula is Age × 2 + 8, and for 7-12 years, the weight formula is Age × 3 + 2.
2. Weight Changes in Boys
The weight of boys changes with age, but the specific growth varies from person to person. At 1 year old, a boy's weight is equal to three times his birth weight, and at 2 years old, it is equal to four times his birth weight. If a child's height and weight growth rate is slow and significantly lower than peers, it is necessary to go to the hospital for examination promptly.
3. Height, Weight, and Development
Generally, the growth of a child's height and weight is related to their development, and genetic factors are also considered. Moreover, the healthy growth of children requires appropriate exercise, adequate nutrition, and good sleep habits. If there are significant abnormalities in a child's height and weight, it is recommended to consult a regular hospital.
