I haven't tried the Lanci or Buddy Belt harnesses, but I was recently turned on to the ChokeFree harness, which I absolutely love.
It was designed by a NASA scientist and is amazing in its simplicity and functionality. But as some of the others say, it might be a little pricey to buy before she gets full grown.
Here's the website and I'll attach a pic.
