Moth orchid has a new plant growing on flower stem

[judy]

I have an orchid (moth) that was given to me and was purchased in a market. It bloomed very nicely for a couple of months. When I trimed the flower stem off leaving about 3 nodules, a new plant started to grow there. I have no idea how to care for this plant. It has two leaves about an inch long and two very short roots. I am leaving it attached to the mother plant. As you can see, I know nothing about orchids but I want to learn. Any help will be appreciated on the care of this new baby.
