First of all, we should teach him to be a man. Don't think that children are young and don't know anything. In fact, he is very clever. No matter what happens, he will learn as soon as he learns. So we must teach him to learn some good things, and tell him to be polite, modest, kind, grateful to his parents, and not to take other people's things casually. These are really easy to teach. When he forms a habit, he will know how to be a good boy.

Then, we should teach him some basic knowledge to lay the foundation for going to school in the future. Usually, you must recite those titles, simple words and simple children's songs. Don't underestimate these. It is always beneficial to study more.

Finally, take him out to broaden his horizons. Don't think that children are safest at home. Just like us adults, children want to go out and have a look, and they are also very novel about the outside world. When he sees more and feels more, his stomach will be filled with more and more ink, which is very useful for children.

Children's three years old is the best stage of education, parents must pay attention!
