Generally speaking, children's behavior and words at dinner, whether good or bad, should be guided and maintained by parents. If the child's behavior is not very good, parents can remind them in time and tell them the correct code of conduct. If children do well, parents can also praise and encourage them appropriately.
However, the way parents protect their children also needs attention. On the one hand, parents should show their high quality in front of their children, behave appropriately, and don't make excessive words and behaviors. On the other hand, parents should also try to avoid interfering too much with their children's words and deeds in public, and can take some slight reminders or private communication to educate them.
To sum up, it is necessary for parents to protect their children while eating, but they should avoid too much interference and inappropriate ways. At the same time, we should also pay attention to children's performance, guide them in time, and improve their family education level and social literacy.
