Hello, I just want to say stop loving your pointsettia. :) One mistake must make is over watering it. The pointsettia is not a plant or flowering plant. It is a tree with leaves, and does not need much water or light during the month of December. Wait for the soil to get about 2 inches of dry dirt. (about to the knuckle of your pointer finger.)
Keep it away from vents, breezes, extreme changes in temperature or humidity. I used the link below to help in my care of the Pointsettia.
