celebgran,,,,,you dont say how old your gran kids are,,,they will surely ask questions when they are old enough,,,might not be when they are eighteen , but when they are older in life,,,,write them a letter and have it put with your will, your family will surely come out of the woodwork when you have gone and then instruct your solicitoer to hand the letter to them personally, you can tell them all what has happened and that you always wanted to see them.leave them a nice photo too, maybe one with your own family in happier times, the presents i would wrap them date them and put them in the cupboard. i had this problem my children didnt want me to see the grandkids,,,,but now they are divorced who did they turn to,,,,,,mum, now i ave them all the time, but i count my blessings everyday,,,because one of my kids said im going to emigrate and get a one way ticket. so that will be another time i wont see the kids but who knows,........children can be cruel...but wait till there kids grow up and hurt them they will know what it feels like to get hurt and maybe they will relize what they did too their parents,...chin up and god bless, they will need you before you need them,....dont worry they will return to the fold,,,,,,i guarentee
