Madgran77, I hold my hands up high, it was I who made the reference to the 'major issue', but only because it had been mentioned previously by someone suggesting that maybe the new mother may have some problems that the paternal grandparents were unaware of. I, too, agree that medical issues are a private matter, and no one wants to broadcast them to the world. But let's get real here, we're talking about parents, and within most normal families, if there are any serious problems, we tend to tell those close to us, who love and care about us. I guess there are many people here who don't have that kind of relationship with their parents or in-laws ... how sad.
Anyway, I think we may have gone off on a tangent here, because none of us know what the reasons are why the OP has not been allowed to meet her grandchild.
