Three-year-old babies basically have the cognitive ability of external things, and they can also react relatively to some external actions, so they can input something at the age of three.

The most important thing is politeness. Politeness is a habit, which is gradually developed. Only by developing this good habit of being polite from an early age can he reflect his high cultivation. Teach him some basic manners, such as greeting elders or neighbors in time and smiling. If your baby does this, he will be praised by others, and others will think that your baby is very sensible.

You can also let him learn some academic things in advance, because a three-year-old baby can enter kindergarten, which is his first contact with the outside world, and it is inevitable that there will be some difficulties in adaptation. If you teach him something to learn in kindergarten in advance, then he can better adapt to the life in kindergarten and get ready for school in advance.

Let him know how to repay kindness, although he may not understand these four words, but you can let him know the truth through some examples, let him know the hard work of his mother raising him, and let him do something he can at ordinary times, which is very helpful for his growth.
