They often get hungry during the course of a morning's worth of active play. The answer, of course, is that we do not know precisely when each person in the classroom will be ready for snack, or how much each will want to eat. Some children eat very large breakfasts and are hungry in the late morning, if at all. Others are too busy playing or sleeping late at home to eat much of anything before school. They may be ready for snack soon after they come in the door.
Some children digest their food very quickly and are as hungry as bears whenever snack occurs.
Others are light or picky eaters. The bottom line is there is not perfect time for everyone to have snack nor is there a perfect amount to serve each person. Nutritionists have been telling us for some time that we are an overweight country. One of the many causes for this national problem is that many of us tend to eat when it is time according to the clock on the wall, not because our bodies are telling us we are hungry. Do we really want to train another generation to eat those crackers and drink that juice just because it is in front of them.
