Hello and Thank You so much for responding. Just be careful what you do and say. I think it is wonderful that the biological mom has done so much to improve her situation and may be a huge part of her children's lives. Everyone involved with the children will have to accept that fact whether they like it or not. Nobody can ever replace your biological mom. There is a bond there that is just so special and remarkably unique. So the other relatives will just have to accept things and take on a different role.
Have a wonderful day!!!
