If the child does not eat vegetables and fruits just like that (surprisingly), try changing the serving. For example, cut vegetables and fruits into shapes, pictures, animals, portraits. The more interesting and appetizing the food looks, the more willingly the child will eat it.
THIS is difficult. My youngest child himself loves them very much from early childhood and eats them. Naturally, if there are a lot of apples, then they get bored over time, and so with any fruit or vegetable. But in general, he loves them and eats them. But the older one hardly absorbs healthy foods, you have to be persuaded to eat at least a little. He will eat an apple - if it is peeled with slices, and then it may not be enough. So it is with berries and everything else. He will give everything to his brother on occasion.
It is, in theory, impossible to force eating. This can cause aversion to food. Rather, act by persuasion and motivation. promise dessert. :)
It is sometimes very difficult to make people eat something that is unfamiliar and unwilling. Try to rebuild the feeding process, add game elements. The original children's tableware can help with this.
You can always find a wide variety of colors and shapes on the website of the Kangaroo online store in the tableware section.
