My son is now 5, and has immediately grasped what the Sorgenfresser is there. Since he can not write, he paints his worries, fears and thoughts. Rumpel she eats then. It's totally cool, because he also explained what he makes me then worrying. And I have a base to help him to cope with that. He must be everywhere and without him it's no longer out of the house! I highly recommend him !!
