It's after 10, and 7 year old Tyler Flores is still awake. "I am not tired and I never will be," Flores said.
Tyler's mom, Sofia Flores, says they've pushed his bedtime to 9:30, but even then he still doesn't go to sleep. She says its taking a toll on the whole family. "In the mornings we always get upset or mad because he's never on time. He's always tired," she said.
A new study shows children who do not have regular bedtimes during the school week are more likely to have behavioral problems by age 7. "Those behavioral problems include things like hyperactivity, emotional problems, conduct problems and problems with their peers," said study author Yvonne Kelly with University College London.
Researchers say going to bed at varying times disrupts a child's developing brain and natural sleep cycles. It's 11:09 and Tyler has just fallen asleep. But some nights his mother says he goes to bed as late as midnight.
Tyler's mom says she doesn't see behavior problems except he is sometimes distracted in school. "He loses concentration easily," she said.
Doctors recommend children Tyler's age get ten to twelve hours of sleep a night.
