I would keep any photographs in albums for the children to look through when they visit or you visit them reminding them of good times you have all had.
Can you set up facetime with them and speak to them every week maybe they will soon remember you after a week or so.
Do you stay at your sons house when you go to visit if you do this will give you quality time with your DGCs and certainly make up for the long distance you are separated by.
I spent over 9yrs living abroad and away from my DGCs and every week wrote to them and posted little cards for them they just loved the Postman calling to the house with a message from nana & grandpa.
A better word than 'apologise'?
