My friends daughter had a bit fear after a fall which wasn't even that bad, but it must've scared her enough to not want to try agin without her parent's help, for fear of falling down again. When she falls, try not to freak out. You could even laugh a bit and high five her for falling if she's not hurt...that may build some of her self esteem and confidence in trying again on her own. Also, if you can use a Jonny Jump-up, that will strengthen her legs and lower back so she is able to hold herself up better when she's walking, which could speed up the walking by herself process. You could hold one end of a towel, and then she can hold the other end, and you won't have to bend down so much and she can still lead herself around and yet, she'll see that you are still sort of holding her because you're holding onto the towel. It might not hurt so much on your back. This will also give her a chance to catch herself when she's about to fall...falling can be a good thing sometimes. They have to learn sometime right?! Good luck.
