Life-size dolls believed to possess the spirits of child angels have become popular in recent months. The dolls, known in Thai as luk thep, are believed to bring good fortune. These dolls are purchased for hundreds of dollars and are blessed by Buddhist monks. Many owners attend to the dolls as if they are their children. Shops are selling clothing, jewelry and beauty treatments for the dolls. A buffet restaurant in the Thai capital, Bangkok, offers them children's meals. But the privileges spent on them have also drawn concern and warning from authorities and psychologists in Thailand. Nattasuda Taephant is director of psychological wellness at Chulalongkorn University. She says if the dolls help their owners feel better, then the fad is rather harmless. But if it crosses the boundary of reality, and they believe they can talk to the luk thep doll, that would be something concerning in terms of mental health."
