I have looked after and cared for all five of my grandchildren for over sixteen years. Now, because of an argument between my daughters, one daughter has banned access to my granddaughter and grandson from that family. Up until the day before the argument, I had the youngest granddaughter (8 years old) every day, and gave her breakfast, got her ready for school and transported her to school. I attended school functions that I was made aware of, cared for her when sick, and had her and her brother (15 years old) throughout all school holidays when their parents were not able to take leave. I have been blocked from her phones, her Facebook, her work email, and her home email. My husband has spoken to her a couple of times, and treated with complete indifference to our pleas to see the children. Although I received pages of poisonous emails from her originally, I have not responded other than to ask to see the children and somehow sort this out. I have sent only very short specific emails or messages, all of which has been unanswered. My concerns are over the children's safety and care on a day to day basis and especially when my daughter goes to London for a couple of weeks later this month (on her own). How is her husband going to be able to get the kids to and from school? Is a 15 year old responsible enough to look after his little sister? I am desperate to see the kids that I love so dearly and I am heartbroken. Do I have any legal grounds ( grandparents rights) under family law for access?
