Aishi, if I were you, I would just let her have some tinned soup when you have it to get her used to it. There are low sodium version perhaps. There were a few times I made Chinese broth (boiling very long time with meat and veg) and DS finished the whole pan and after a few times, he just didn't want more than a small cup, because I tried to change things up and adding more veg, etc. counterproductive here really.
It reminds me to make the exact same soup as the first time and see if he still likes it.
