What to do when sleep is elusive?

The summer heat has impacting sleep patterns recently, and with parents trying to get their children back into regular bedtimes compatible with the school year, we're looking at some solutions. Sleep researcher and child psychologist Sarah Blunden says sleep is one of the most challenging issues parents face - from unsettled babies, toddlers changing sleep patterns - and then there are the teenage years and young lives dominated by screen use. Dr Blunden is the founder of the Australian Centre for Education in Sleep, and also directs the Paediatric Sleep Clinic based in Adelaide.
