Will you? I dont think I would, as I dont think I would be able to equally love both the adopted and biological.
When giving birth to my second, biological daughter, I worried that it might be challenging to love her as much as my first. Then, I laid eyes on her for the first time and the same "book" that opened in my mind and heart with my oldest opened. All the love and desire to care for her as deeply and thoroughly as the first baby, flooded over me.
I can say with honesty, I love them each the same, but, uniquely, as they are unique individuals.
When caring for my niece, I love and protect her as if she were my own, though, she's not my baby.
I could totally parent and love a child that isn't mine, biologically.
