I like Lottie but I really like having options so personally I would try to think of another name that it's the shortened version of - if not Violet, what about Violetta?

After much head-scratching, I called DD Katrina. Initially, we called her Kittykat, after a few months she graduated to Kitty and now at nearly two, we're thinking about using her full name. But when she's older, she can choose to use Kitty, Kat, Katie, Trina or Katrina or maybe even Rina. But that's just me, I'm a bit addicted to having options!
