This is also true of foods like french fries, chips, or cookies. As long as other nutrient requirements are met, extra calories usually won't hurt an active child. Remember that children model their parents, teachers, and other older children and adults. If you choose healthy snacks for yourself, a child who is watching will learn about good eating habits. If the snacks are nutritious, you are helping make sure that nutritional needs are being met.
Preschoolers have widely fluctuating food intakes.
Don't force a child to eat. They need to learn to eat when their bodies tell them they're hungry. And don't let children use food to manipulate you. Parents and teachers can provide food, but it is up to the child to eat it. This attitude provides a balance between the structure of mealtime and freedom of choice.
