After preparing a nutritious and tasty lunch for your little one, the last thing you want to see at the end of the school day is a lunchbox still containing that same lunch. The waste of food, not to mention the time in the kitchen, is an obvious issue, but uneaten lunches can be a real worry if it starts to become a daily occurrence for your child. If a child is not eating their lunch they may feel sluggish and unable to concentrate in school. Small children especially may become irritable and tired, which may lead to behavioural problems in the classroom and yard.
