The ability to filter out distractions and sustain attention to tasks that may have little or no personal meaning is a difficult skill for many of us. Often, out of lack of knowledge and frustration, we resort to demanding a child's attention. Sometimes we fall into the belief that if we can have them sit still and pay attention in circle time for ten minutes when they are two years old that they will be prepared for a 20 minute circle time at age four. Attention is a complex skill that does not develop through stamina training.
