I'm thankful my parents have saved so many books from our childhood. Kieran discovered the book Mr Puffer-Bill - Train Engineer by Leone Arlandson. It's rather beat-up by now, having survived my siblings and me and then the grandkids, but that just shows how well-loved it is. I should have known Kieran would love it given his love of trains. You can still buy used copies on Amazon, but I don't think it's being printed any more. It's a fun book, though, following Mr Puffer-Bill as he tries to find a hat that will stay on his head to protect him from the rain.
