It's amazing how sensitive these little guys are to what they are eating. Next we look at the style in which all of the child's role models are relating to him. Then we come up with a plan. Young children are looking for mentors, and examples in life. They are also looking for opportunity in which to grow and above all, teachers who will take the time to know them and learn to understand their unique learning style.
Some children are just more physical than others.
They need a broader base of gross motor activities to start out their day before they can actually sit down and master a task that requires greater mind and body control. There might be something about the classroom dynamic that is agitating your son. Please don't feel inadequate. You sound like a very supportive, insightful, and concerned mom. It sounds like the staff are focusing on the perceived problems rather than on a solution for your little guy.
