Hi Marcey
I'm happy to hear you removed the keiki. It's roots were definitely long enough (they shouldn't be removed until the roots are 2-3" long). The plant looks stressed and the keiki was most likely not doing anything to help it recover.
I don't like sphag for most chids, I'd repot this one into some bark (I use aliflor or Hydroton but most folks use bark). Remove it from the sphag, check the roots, remove any brown mushy roots with a sterile clipper and put it in fresh bark.
Without the plant having a name, we can't really know for sure if it's the type that needs a winter rest...but even if we knew that it did I'd recommend continual care for it until it's happy again.
What is your watering/feeding schedule? Lighting?
