Welcome all to the world of grand-parenting. The lovely thing is that you can have all the fun and then give them back at the end when you're exhausted. I've got my first nursery Christmas Concert later this month watching my twin grandson and granddaughter (aged 3) do their bits. Though I still remember having to comfort my younger daughter when she was about five when she was cast as the back end of a donkey. "I wouldn't have minded if I'd been the front end dad," she sobbed. Now she's in her thirties and trying for kids of her own.
