You might want to piggyback with the NEA Read Across Ameria. They hook it to Dr. Seuss' birthday, March 2. http://www.nea.org/readacross/
It would be fun to have various Dr. Seuss stories read in rooms to kids in pajamas--readers in pjs, too. Parents might listen to one story and then visit a room for information on reading to/with your child and how to support them in developing literacy.
Our school does something similar also in December with holiday/winter stories and sharing dessert after.
