is it really that difficult to understand that telling a little girl her mother didn't want her is different from telling an adult woman the same truth? Yes. it will hurt in both scenarios but the psychological capacities of a child and a mature woman differs so greatly, not considering it is absolute stupidity.
I am so sick of this cliche plot in which children blame their parents for such cases. And it is just wrong. And how the girl starts paying attention and fascination to her newly found mom like a little kid who has found a new toy is just so childish and immature. Ignore the parents who had stayed with you, loved you, taken care of you and go play with the new parent! How mature is that!
