I recently wrote, for the Washington Post limerick contest, a limerick on "blanky" and yet a different one for the OEDILF on "blankie." However, the word is not in the OED or Onelook...and I wondered why. Doesn't everyone (at least in the U.S.) know what a "blankie" is? I looked in Google today and found 117,000 sites for "blankie," 42,400 for "blanky," and 11,000 for "blankee."

Don't you think "blankie" should be in the dictionary?

Of course! A blankie is a blanket, except has special emotional attachment for a child. Often it is the blanket you had as a child and carry around at a later age, or at least still have in your room somewhere.
