Worry dolls, or trouble dolls, are very small dolls originally made in Guatemala. A person who cannot sleep due to worrying can place a worry doll under the pillow; the doll is thought to worry in the person's place, thereby permitting the person to sleep. In the morning the children wake up without their worries, which have been taken away by the dolls during the night. The dolls are about 1/2 inch (13 mm) tall and handmade from cotton, wood and cardboard.
I have dozens of these and hence, very few worries. They come in both male and female attire and a wide variety of colored fabrics are used in creating them.
