Nope, doesn't bother me a bit. I just correct them (and usually get that deer-in-the-headlights look in response) and move on. They can call them anything they want - it doesn't change the fact that they are QUILTS, not blankets, although in the cartoon Linus always had his "blanket". Maybe that's why they call them blankets. This is not a problem worth fretting about. :)
