i have my first phal keiki growing now too, and it also had flowers growing from its first few leaves. i think technically they are growing form the stem form the mother plant, as there is no stem coming form the keiki. it should be harmless. mine eventually faded, but the keiki is still growing and has some roots now. and the mother plant has a new spike beginning to open more flowers. does not seem to have bothered the mother of the baby plant.
