At this time, the three-year-old baby has his own cognition, but in the final analysis, he is still a baby, and his daily diet needs parental supervision, so as to better ensure his development. Then, let's look at the weight and height standards of a three-year-old baby.

1. The height and weight standards of three-year-old babies will be different due to gender differences. Generally, a three-year-old boy is about 89.1cm-103.1cm and weighs about11.4kg-18.1kg. The height of a three-year-old female baby is roughly in the range of 87.9 cm-102.2 cm, and the weight standard is also11kg-17.8 kg. It is normal that male babies will appear taller and heavier than female babies, which is a physiological difference between men and women.

2. The three-year-old baby has entered infancy, and the baby has a certain thinking ability, and can make his own judgment and thinking about the things around him. At the same time, at this time, some babies who speak faster already have the basic language expression ability and the ability to recognize the surrounding objects, and gradually realize the rules in the game.

We often talk about enlightenment education. In fact, a three-year-old baby can start enlightenment education, whether it is mom and dad tutoring or going to some special early education institutions.
