My 2 grandchildren ( 3 & 6) live with my son and wife in Japan!
I have seen them twice since they were born pre pandemic. Since then we keep contact on FB Messenger, almost daily with my son wh keeps me informed of ther progress and outings, etc, on occasions with the children themselves, which is often difficult due to time difference, and two children trying to outdo each other for attention! I’m not well enough to travel out there ( and couldn’t yet anyway due to restrictions, his brother has wanted to get out for ages) and they can’t just all travel over here! Money, time and currently travel restrictions,
I am content with the situation I can’t do anything about…I have my own life and business here, and at 76 am in poor health. My son has just left a very well paid job and is now doing a boot camp in another field of work.
My ex remarried some 22 years ago and is constantly complaining of lack of contact and basically due to his general judgemental mode actually drove them away to live in Japan as far away from him as they could get just before the first child was born - he has many many times said “ he is no son of mine”,” I will disown you” etc, etc, whilst at the same time complaining that they have little contact…..
So - enjoy what time you have with the grandchildren, even if it seems too small to you. If you give, without ‘wanting’ - they, and your son will be so much more likely to WANT to do more with you… keep complaining and they may move away or similar… !
Do what others have said- basically get a life without them, the more content you will are in yourselves, the more likely the grandchildren and parents will WANT to see you.
With this current attitude you will lose them completely…!
