1. Diversified food choices: provide children with different types of food, such as vegetables, fruits, protein and carbohydrates. Children can participate in the selection and preparation of food and make them feel more interested.

2. Add new foods slowly: When giving children new foods, introduce them slowly, try only one new food at a time, and let children participate in the food selection process as much as possible. If children don't like a certain food, don't force them to eat it, but try it many times.

3. Set an example: Children often imitate the eating habits of adults, so adults should set an example. Maintain healthy eating habits and let children see that they are eating healthy food. They may be more willing to try new foods.

4. Give children a certain choice: Try to involve children in diet decisions and give them some limited choices, such as letting them decide what to eat today or how much they want to eat. This can increase children's interest and participation.

5. Use games: Some children may prefer playing to eating, so games can be used to attract them. For example, cutting food into interesting shapes or asking them to put food into interesting shapes can make eating more interesting.

In short, it takes patience and skill to deal with children's picky eaters, and it is necessary to try different methods to find a method suitable for children. It is important to give children a variety of choices, slowly add new foods, and try to involve them in diet decision-making and preparation.
