Getting a good night sleep can be tough on a sticky summer night. It can be even harder for young kids - and their parents! - whose sleep schedules have been put out of whack by holiday adventures and longer daylight hours.

And as the end of the holidays approach and a return to school looms what are some of the ways to get back into a good sleep routine?
