Marilyn would walk and wobble and fall over when she first used it. You want it where you can get your index, middle and ring finger under it but snug, not loose. :)
Oh now I can see it! Is she a little lopsided? Looks like she is going to the right a little bit hehehe...it only took Marilyn 2 days. I left the harness on her for a few hours at a time and then the 2nd night the whole time and she was ready to go!
