The Mother
I completely understand the concept behind the mother wanting to do right by this child and the child's mother, especially if there was some sign of this being an involuntary adoption...
But majority of these families wait on a list for years before there's an available child to adopt, along with the time spent trying to conceive children of their own.
She seemed so passionate about finding the daughter's real story and didn't seem too concerned about the fact that she would be forced to give up the child she had adopted to be her own daughter. She immediately found out that the daughter's birth weight was low, and that led her to be so willing to give the child back? I just don't know how much I believe that a mother, who's finally been given the chance the raise a daughter, would be so eager to find out that it's not a legal adoption and give her away. Whether or not it's the right thing to do, ignorance is bliss sometimes. And I feel like an adoptive parent who went through a reputable agency wouldn't even have considered going down this road. Especially not with the only initial sign being in the lower weight percentile...
