Hi  Cherry:  So sorry for what is happening. It does suck and kids are smart and do pick up on these situations. We have been through the same type of thing. My mother in law did not accept our oldest daughter because she was not a birth child of her son. Now that we have adopted another child she is not accepting of her either. In her mind birth children are different and she worships the ground they walk on. We always let our kids talk about what was going on and how they felt about the situation. As they got older their Grandmother has been joked about quite a bit. Humor is a good outlet. One good thing is that this has not caused any hard feelings between the kids and they are not jeaslous of the relationship birth girls have with their grandmother. We have always surrounded all our children with lots & lots of people who do love and cherish them. Our attitude is that; it is Grandmothers loss and we have taught the kids that they are not at fault for her shortcomings. Seems like this is a common problem especially with older generations. I doubt if it is CAH related as these types of grandmothers usually find any reason not to get close if it affects their comfort level. Chin up.... Your grandaughter knows she is loved by the people who really matter in her life!
