Parents should solve the problem from the root. If children eat snacks before meals, they can't eat too much, and they can eat less next time. If the child doesn't know how to deal with the unfinished meal, then teach the child not to know how to solve it and ask the parents. In order to let children learn a lesson, they can be hungry, and there is no need to pick up the leftovers in the trash can to eat.

Cultivate correct ideas

Conceptually, let children know that food is hard to come by, and let children know how to cherish food. Over time, children can remember the correct concepts.

Establish principles

When children are young, parents can make principles for their children, such as how much to eat, not throwing leftovers, eating leftovers by themselves and so on. Parents should not waste food, let alone help their children eat leftovers. Parents can urge children to eat as much as possible according to the situation.

Set a good example

Whether eating out or at home, parents should set a good example for their children. Usually the family goes out to eat, orders less, and packs leftovers. When eating buffet, teach children to eat as much as they want, and don't waste food if they don't eat enough.
