It's likely at least some kids out trick-or-treating last night will have trouble getting to bed today, but a University of British Columbia researcher says kids' sleep troubles go beyond post-Halloween sugar highs.

UBC nursing professor Wendy Hall said about one-quarter of Canadian children have trouble sleeping, and that usually leads to sleep-deprived parents.

"You can imagine that parents can start to feel very fatigued and depressed and just not very well," she said.

For the past five years, Hall and her team have been working on a sleep-improvement tool for parents.

She says her month-long program — Better Nights, Better Days — requires parents and children to complete several video exercises online.

The exercises cover elements of healthy sleep, common sleep problems, a sleep diary, and other methods to help children develop better sleeping habits.

"It's very interactive and there's a lot of components in it," she said. "So it talks about what normal sleep for kids is and what all the factors are you can [use to] promote normal sleep for kids."

The program is running as a pilot across Canada and a stipend will be offered to parents for completing it.

Parents of children aged one to 10 are eligible and can register online.
