The height and weight of 1-year-old infants are different between men and women, with the height standard for boys ranging from 71.3-80.3 cm and weight from 7.9-11.8 kg, and the height standard for girls ranging from 69.2-78.9 cm and weight from 7.1-11.3 kg. However, there are individual differences. The height and weight of boys are slightly more than that of girls, but they are not fixed, there are individual differences, and the height and weight standards can be used as a reference. Normally, the height standard for a 1-year-old boy is 71.3-80.3cm and his weight is 7.9-11.8kg, while the height standard for a girl is 69.2-78.9cm and her weight is 7.1-11.3kg. Because the child’s height and weight have a lot to do with heredity, as long as the child’s growth and development is not abnormal, the standard can only be used as a reference. It is recommended to keep an eye on your child’s growth, and if your child’s height and weight are significantly different from that of babies of the same age, it is recommended that you seek medical attention in a timely manner.
