Hi Gama, I feel for you as I am in the same position, it is so cruel when you get attached to grandchildren and then you are denied the right to see them.
I have a one-year-old granddaughter and my daughter got married last weekend and I was never told or invited because his parents and her Dad who have been nasty to me over a family rift some years ago, paid for the wedding, and said that I was to be excluded because of them paying for the wedding. I was told by my daughter that she and her fiance and my granddaughter were going the wedding of her fiance's cousin and that my granddaughter was a flower girl at the wedding, I asked for a photo of her in her Flowergirl outfit and she looked adorable when I saw it in a message via Facebook and said how I would have loved to have seen her in real life in that outfit, little did I know it was my daughters wedding at the time, but now I have found out all hell has broken loose and my side of the family has disowned her, or so they say - I have my doubts, but now I won't be able to see my Granddaughter.
I was wondering if you had considered like I have if you could arrange a way of seeing your grandchildren via an impartial 3rd party, like a Social worker at a Social Services office? Many such services are oversubscribed so they may not have the means to help like this but is it worth asking? Our grandchildren are innocents in all of this and they will be having to do without us in their lives which isn't fair on them and what sort of role model are the parents who deny their parents from seeing their grandchildren, not good ones, so if you can be a moral compass for any grandchildren that is good isn't it?
Life is so unkind and cruel the world is a dangerous place so the more people that can protect a young life the better. Has anyone else got any ideas on how to resolve this sort of predicament, when any amicability isn't forthcoming from the parents of the little one?
