I'm not sure when D.D. became real, but I'm fairly certain it happened within the last year. D.D. is my daughter's very first security buddy and has been with her for most of her four years.
Some kids have blankets, and others have stuffed animals.
My security blanket was probably considered a biohazard by the time I gave it up. Now it is a sort of a grungy, grayish blue. We're pretty sure the name D.D. came about as her first attempt at the word Teddy. The tag was the first part of D.D. to actually look worn. She continued to stroke the spot where the tag used to be and eventually wore a hole in the fabric.
