Question
Many thanks for the prompt reply,

As this new plant has only 1 short root, 2" approx, should I wait till it has more?
If I leave it on the mother plant, will it flower soon, and how often should I feed it now? If I remove it, how do I get the mother plant to flower again, or has she stopped? She has an extensive root system in a pot  4" X 4" deep.

Thankyou in advance. Also please post this on the noticeboard, if it can hlp other enthuasists

Answer
The mother plant will likely wait until its next flowering cycle (ie when it normally flowers) to send out another flower spike.  As long as the keiki is doing well, I would wait to remove it, especially if the mother plant is putting out strong new growth.  At this point the keiki has its own leaves and is not drawing heavily on the resources of the mother plant. I would wait until it has at least three roots to remove it.  If the keiki flowers, likely it will flower about the same time as the mother plant.  Removal of the keiki will not affect the flowering cycle of the mother plant.  When you feed the mother plant, try to feed whatever root(s) the keiki has.  Wet the root until the entire root turns green.  You may best do this by dipping the root in a small container having a weak concentration of plant food to avoid getting water into the leaf axils of the mother plant.  Sounds like you're doing  good job-- keep up the good work.
