I gave up full time work to look after my granddaughter for 4 years, even when her mother was on maternity leave with the 2nd grandchild. We had her from 7 p.m. one evening of the week until 7 p.m. the following evening. She is a lovely child and very well behaved. However things changed one day when we were asked to babysit one Saturday night. We agreed to collect the children at 4. p.m. so they could get ready, have both children overnight and then would drop them off the next day at 10:00. This went down like a pricked balloon as my son complained, we don't ask you to have them that often on a weekend. I wanted a blow out and 10:00 is a bit early. What he really wanted was for us to have them both all day and neither my son or his partner liked it. He hasn't spoken to us since August 2021. I believe he has had too much support, emotionally, financially and practically and expects, expects, expects. He is depriving us from seeing our grandchildren as well as him and it is heartbreaking. However until he finds it in his heart to apologise and accept that we have a life too (we are both 62), things may not change. I have tried writing to him, but he has ignored it, has returned birthday gifts and blocked us from phoning him. We have done so much for him, that it would read like a book, and all has been forgotten. We are now estranged and I cannot see how we can get beyond it apart from wait and see. Such selfish, callous behaviour.
