A snack is a refreshment eaten between meals. It is smaller than a meal and can be something to eat, something to drink, or both. Because young children cannot eat a lot at one time, they need one or more snacks throughout the day.
Snacks are important because they give children energy.
Boys and girls grow fast and they use a lot of energy when they run and play. Using energy makes children hungry. It is hard for them to wait until mealtime. Snack times help keep children from becoming overly-tired and grumpy. They also help children slow down and rest.
