The Hospital for Sick Children is currently recruiting kids from across the country to participate in a sleep study called “Better Nights, Better Days,” reports CTV News.

For many parents, getting their kids to bed every night can be an absolute struggle.

Michelle Wan is one of them. Her 6-year-old son Ben just won’t fall asleep.

“I would say around (the ages of) three or four, once he started getting aware of everything else in his room, he started getting distracted and it was a bit hard to put him to bed,” Wan told CTV Toronto.
