I think there is good research that shows that nutrition is critical for a child's brain and for concentration and learning at school. So whether breakfast is provided at home or at school, as a pediatrician, I do see a difference in kids that get good nutrition in the morning, such as protein, fresh fruit and enough calories, and how they function during the day at school, while adults may be able to focus and concentrate better with poorer nutrition, with kids, they cannot necessarily control that, and they might be more distracted and less able to sit and learn if their basic needs such as sleep and nutrition aren't getting met.
