Let's see how old the child is. If it is a child around 3 years old, it means that the child may find it very fun. 3 years old is a sensitive period for making rules for children and needs to be corrected in time. Then when he started to knock, he took the bowl away, replaced it with a toy piano that could be knocked, and said, "Baby, you can't knock on the bowl while eating. Mom, if you don't want to eat now, just play for a while. " When he knocked for a while, he asked him, "Are you enough? If you feel hungry and want to eat now, mom will bring you rice. " So you can't knock on the bowl when you eat, and you can't eat when you knock on the bowl.
If it is an older child, it may be that the child has developed a bad habit, and the family did not correct it in time at the beginning. First, ask the child why he knocks on the bowl while eating. The child will say what he thinks of doing this, maybe he hasn't realized that it is a bad habit. At this time, it is necessary to reason with him and explain that it is an offensive and uncivilized behavior to knock on the bowl while eating, which will disturb others to eat. If you do this when eating at someone else's house, people will think that you are a child without quality. In addition, if mom and dad deliberately do things you don't like in front of you, are you also very uncomfortable?
