Hmm. I think I saw this one as _The Juniper Tree_ in which the kid comes back as a bird first.

  My mother, she killed me, my father, he ate me,
  My sister Marlene gathered all my bones,
  Tied them in a silken scarf,
  Laid them beneath the juniper tree,
  Tweet, tweet, what a beautiful bird am I.

(Grimm 47, Aarne–Thompson type 720, "my mother slew me, my father ate me")

Remember that plenty of the original Grimm stories had been meant to entertain adults, too.
