Though the narration is maybe a little simplistic by 21st century standards, this is still quite an interesting short documentary that looks at the importance of sleep and at the significance to a child's development if/when it's interrupted. Adults can often rationalise what is keeping them awake - a pain or a problem that will require sorting in the morning. That's often not the case when we are younger and this feature plays out a few scenarios where a child might be over-wrought or worried or frightened. It might not be such a palpable fear either - perhaps under or over-parenting might be the cause, or uncertainty about how to behave? It's all a very middle class exercise so maybe isn't the most representative as we see well fed/clothed children put safely to bed each evening, but it does ask a few questions that might be even more relevant nowadays when youngsters have almost unlimited stimuli to influence their sleeping patterns. An early look at what makes kids tick and it's worth a look.
