Hello, you can encourage him with verbal and food toy rewards,Appropriate praise for the child can increase the child's self-confidence, when the child is praised, invariably feel affirmed, so it will produce self-confidence.
Children who are praised by their parents from time to time will be more agreeable to what mom and dad say, so they will also care more about the family and affection, so it can enhance the relationship between parents and children and warm up the feelings. It also affects a child's motivation to learn. A child who is often praised is more adventurous and tries new things, so he or she will be more proactive in learning, and usually gets better grades, but if the child is often scolded and denied, it will easily affect his or her mindset to learn new things.
However, you can't praise them too much or in a vague way. Excessive praise for the child is very easy to give the child the illusion that he is perfect, the child will not be able to see their own shortcomings and mistakes, and may even feel that he has left other children far behind, the child will be proud and arrogant, and even egotistical. And similar to the "you are great", "you are smart" vague praise, the child may be happy to hear at first, but listen to more, will feel that the parents do not go to the heart, and even think that the parents are hypocritical. The fact is that the child is not a good person, but he or she is a good person, and he or she is not a good person.
From the child's point of view, if they are often praised for being smart, they will think that they are a smart person, and being smart is a person's talent, which means that I don't have to put in too much effort to accomplish something easily. To try a new or harder challenge means there is a chance of failure, and failure takes away the label of smart.
If we encourage and praise our children for their efforts, they will think that it is because they put in enough effort to achieve good results, and will not be afraid to take on challenges. Even if they meet with failures, they will take it for granted that this is a normal part of the road to success, and will not discourage the child from continuing to work hard.
