Appropriate punishment
If the child is willful and doesn't eat well, parents don't have to waste their breath and take all the food away after dinner time. Don't worry about starving children, not eating two meals at a time will not affect the growth and development of children.
Appropriate reward
In the process of behavioral intervention, children who behave well should be given appropriate rewards, such as hugs, verbal praise, material rewards, etc. However, it should be noted that the material rewards should not be too much or too big, otherwise it will soon become invalid.
