Hi if I can chip in from a Physiotherapist / Feldenkrais practitioner perspective. Your posting warmed me, because of your comment that your daughter asks to 'walk'. Wanting to do something is a powerful place to be. She sounds very motivated, and if she want to do something, I'm sure she will, in her own time.

However, it maybe she doesn't have the buidling blocks in place to accomplish walking independently. We all go through developmental stages and steps, and a tour of the internet will swiftly enable you as a parent to identify where she is at. Can she roll over? Sit independently? Crawl? Is she weak all over? or are her legs weaker than her arms? Does she cruise the furniture? Is one side weaker? Does she has some toys that you can buy easily on the net to help her? Like this site

or like this rocker horse


From your comments I am not sure if you are a Physiotherapist, or here seeking advice.
However, as a parent, I do know that all children are different and have their own specialisms, not all of which need strong muscles. It sounds from your comments that she is beginning to speak, which is quite early, so perhaps she will have an area of specialism to compensate for her otherwise not so great side. She will still be exploring, but maybe she is exploring more with her cognitive aspects. Movement enables us to fall down, and go to touch things we want to, it raises visual field, opens us to a bigger world,

Just a tip, wherever you are in the World, you will almost certainly be able to find a Physiotherapist, who is also a Feldenkrais practitioner, and you may wish to explore this slightly different empowering approach. However, there are also many Feldenkrais Practs, who are not Physiotherapists, and all will have something to give.
Feldenkrais practitioners work with the entire individual and not the 'condition'
Good luck
