I've heard it all now. I was travelling back from Cardiff on a train out of Chester when a Grandma and her two grand daughters aged about 5 years and 3 years old sat across from me. As we got moving the grandma asked the elder grand daughter whether the younger one still had a dummy to go to sleep with. The elder grand daughter said "yes because if she doesn't have one then she keeps moaning and that makes me so f***ing cross". The Grandma did and said absolutely nothing!
