Cover art for A Bird's Song lyrics by Ingrid Michaelson

Hmm. I agree with those who said it was about a mother not being able to keep her child. I think the line "I'm saving you the best way I know how" has something to do with the mother knowing that if her child is kept with her, the child wouldn't have a good life. So she's saving her child the best way she knows how by giving them away.
