I really feel for them. I have a similar situation. 4 grandchildren, probably 5 now as a neighbour found a photo of my youngest, heavily pregnant, on Facebook. I found our about my other grandchildren via Facebook too, before my children realised and blocked me and all my friends. I put cards and small gifts for each of the grandchildren in a box on Birthdays, Christmas, Easter etc. to be given to them, either when I am pushing up daisies, or if they ever find out about me and come to find me. Christmas passes by in anxious days,
This year, after nearly 11 years, was the first time we didn't send birthday presents to our GCs and we won't send Xmas presents either. In all these years there has not been a word. The last time we saw them they were little children now they are teenagers and probably don't remember us at all.
Instead we buy a small cake and light a candle on it on their birthday, remembering them in our own way. Will light a candle for them at Xmas as well.
I really feel for you
I know how hollowed out this sadness makes us feel sometimes, but you are not alone.
All the best.
