These dolls are not for playing – these dolls are enchanted.
In the evening, before going to sleep, you pick up a doll, surround her with your hand and tell her about your sorrows, like about the broken cup and the fear of getting grumbled by mommy, about the children you got teased from, about the granny who got sick. 
About, how mommy and daddy got into a fight and everything else which concerns the children's heart and soul.
Then you put them under your pillow and fall asleep peacefully.
It is your great-grandmother, your great-grandfather and your invisible family who protect you. 
And for us parents it's the awareness of the healing effect, that consists of children speaking about their problems and trusting the power of protection, instead of swallowing them.
This is a special gift, not only for little ones but also for parents.
