The median height and weight of boys just over 4 years old are 104. 1cm and 16.64kg, respectively. The height and weight of boys aged 4.5 years old range from104.9 cm to15.7 cm.
The curve of children's growth and development can visually reflect the level of children's growth and development, which is conducive to the dynamic monitoring of children's growth and development. If it is found that the height and weight curve of children is obviously deviated from or lower than the normal level, we should actively find out the reasons and give necessary intervention and treatment.
Personality of four-year-old children
Three-year-old children are gentle at heart, and four-year-old children are lively at heart. A typical four-year-old likes adventure, hiking and excitement. He likes anything new, knows people he doesn't know, visits new places, plays new games, toys, activities and books. No one responds more positively to the entertainment ideas put forward by adults than him.
No matter what ideas you come up with, a four-year-old child will happily accept your proposal without comment, so it is a happy thing to give children of this age new toys, books, clothes, experiences or information. Because no matter what you give him, his eyes will shine.
