I'm just wondering if it would be a good idea to expose her to more people and traffic. I don't necessarily mean during her walks, but a trip into town maybe, every now and again, seems to me that the more you expose them to things ( as long as they don't get frightened) the quicker they calm down. If they don't have experiences, then everything is a distraction for well into their lives.
They are so inquisitive of all things new, and Pippin sounds more so than most
