(UPI) -- - Behavioral treatments are an effective way to resolve a child's bedtime problems and night wakings, according to U.S. researchers.

Jodi A. Mindell of St. Joseph's University in Philadelphia reviewed 52 treatment studies involving 2,500 infants and toddlers.

"The results indicate that behavioral therapies produce reliable and durable changes in bedtime problems and night wakings in infants and children," wrote Mindell. "Across all studies, 94 percent report that behavioral interventions produced clinically significant improvements in bedtime problems and/or night wakings. Approximately 82 percent of children benefit from treatment and the majority maintain these results for three to six months."

The studies show that 20 percent to 30 percent of young children have significant bedtime problems and/or night wakings, according to the study published in the journal Sleep.

However, to get children to go to sleep it's recommended that consistent bedtime routine be observed. In addition, establish a relaxing setting at bedtime, interact with children at bedtime, keep children away from inappropriate media, and don't let a child fall asleep while being held or fed. Experts say school-age children should get 10 to 11 hours of sleep a night
