Ernst has won from the first day to the full "confidence" of our 7 year old son. Due to the switch from kindergarten to school (new situation, new people, new challenges), he got nightmares :-( Ernst eats at them and already is provided for a quiet night. Every evening before falling asleep talk my son into the "Sorgenmündchen" his desire to have nightmares. And it works. Since Ernst living in the children's room, nightmare monsters have no chance !!
