Hey......call me BREAD !!!!!!!!!!!

Does every kid make up names for themselves? I wonder. My son likes to make a name for himself every week or so. He was, spiderman, superman, batman, optimus prime, and now Fred. The only problem is, he has a speech impediment. When he says the "F" sound. It comes out like "B". So........He's been yelling at me lately when I call him by his name(Bruce). He's like you call me Bread!!! He's trying to say Fred. I think I like Bread better. Yea...Bread. When he was born I tried to convince my wife to let me name him Darth. Imagine the fear that would have on kids. He would NEVER get picked on. NOT that he will as he is twice the size of most kids his age.
