Why can’t brilliant children switch their minds off and sleep? Thwarted creativity. If the need to play a musical instrument or write poetry has no outlet, this energy has nowhere to go. It can’t be coaxed into some other channel, but must be satisfied.
Until parents and teachers realize this, insomnia is likely to be a problem, but with observation and encouragement, we can discover both the focus of a child’s creative drive and also how to direct it. Then, and possibly not before, we can expect insomnia to subside.
