Hi, I'm hoping my computer doesn't freeze up before I get to tell you what a wonderful adoptive couple you are.
You show such love and caring for your children.
You have been wonderful to both the birth mother as I know inside you feel what a wonderful GIFT she has given you. I applaud your unselfishness by letting your daughter explore who her biological mother is. As she grows older she will realize what a wonderful woman the person who adopted her has been to her all her life and will thank you for letting her know where her roots began.
Of course they will always be your children as you are the one that parents them.
I just wanted you to know how touching your story was and what a wonderful person you are. It shines right through in the words of your letter.
