>>>we are reminded of this terrible mistake each and every time we look at her<<<
This wording is so wrong is so many ways.
For the sake of the child, they've got to stop this. My kids don't "look like" me and two have dark skin - I'm an adoptive parent. Those kids have enough issues to deal with when they are wholeheartedly loved for who they are - she sure doesn't need her mom telling the world she was a "mistake"!
