My keiki is dying

[Mercedesrb]

Hello! My name is Mercedes, I am new to this forum. I was hoping that some of you more experience orchids care givers can help me.
I do not know the name of my orchid but it had big white flowers and was doing great for 3 years. During the summer grew 2 keikis but the mom started to dye. I have not move the plant and I have 2 other orchids side by side that are thriving...
I have been waiting for a while for the keikis to grow roots but one of them has already died and the second one is starting to loose consistency in the leaves (getting softer) i want to save the second one. The mom is completely dry. What should i do? Should pot it? Help!
Eternally grateful!
M.
