Hello
Miniature Phalaenopsis sounds right to me.
Without a definite label it may be impossible to find out it's true lineage, but I have seen quite a few miniature Phals for sale a round the various places recently.
If it is flowering I would doubt that it is a baby plant, but can not say with absolute certainty (Still consider myself relatively new to the wonderful world or orchids).
Phals species can vary a lot in size from one to the next, let alone within the vast quantity of Hybrids and Noids that have been derived from the originals. Also check out the Phalaenopsis section of this Forum, it has some interesting info, pictures and links should you wish to learn more.
If you have a picture that would be of extra help in identifying the plant. But my guess is your assumption is correct.
And remember, there are no stupid questions
