"D" the Ducky

Yesterday, I picked up a stuffed yellow duck up to show Hunter while in the check out line at Kohl's.  Hunter was immediately smitten.  Hunter either calls him "D" or "Quack or Quack."  He can say duck, but I don't think he is as comfortable saying it as he is the other two names.  He wants to know where the duck is at all times.  Hunter even tried to feed "D" his breakfast this morning.  He hugs on him and grabs him when it is time to get in the car or to go upstairs.
