Keiki attached to a yellow stem.. should I repot the baby?

[dzchaser]

Many thanks to all for the feedback. We have since repotted our keiki and she is flourishing in her new pot. The hubby and I don't use any keiki-paste; that's actually the first time I've ever heard of such a thing. We just keep our plants well watered (once the top layer of moss is dry, we water all the pots; we have five now, up from our original two) and expose all plants to filtered sunlight during the day.

Unfortunately, for us, it looks like momma plant isn't doing too well. her leaves have really started to yellow severely, so we fear that the other flowering keiki may need to be removed... is there anything else that we can do to rescue momma plant? We recently gave them all some Schultz Orchid food.

I really appreciate all the feedback to date; please take a look at my photos and let us know what you think is happening!

Thanks again!
