It may've been an anthology of scandinavian folklore? One of the stories was a woman tricking a forest god into teaching her magic in exchange for her telling him how she stayed dry in the rain, another was a mother giving away her son to an old dude and they made a deal that if she came back in a few years she could take her son back. Problem was the dude transformed her son into a bird and put him in a bird cage with other same-looking birds. All he said was "you're his mother, you should recognize him" or something.
