Hello, although parents should set an example in the process of educating their children, when children waste food, being parents is not necessarily the right way of education. The reason for this is mainly based on the following reasons:

First of all, when their children waste food, parents take this way to educate their children. Although it can shock children's hearts to a certain extent and make them feel guilty about their food waste, parents also have some show and exaggeration to avoid it. After all, children nowadays are more sensible in most cases. Parents can explain to their children the importance of cherishing food and point out the mistakes of children's food-wasting behavior, which can also play a good educational role.

Moreover, in order to educate children well and not waste food, parents' expectations can be met not only through this thing. The purpose should be that parents should always supervise their children's daily behavior during their growth, and parents should correct them in time when their children waste food. After a long time, they will let their children form the good habit of cherishing food and will not waste food again. Personally, this kind of education effect is obviously more effective and lasting than the previous one. For children, learning to cherish food without wasting food requires a process of habit formation, and parents should be patient enough.

So I don't think this method is appropriate.
