I'm the youngest of 4 children, and the youngest in the entire extended family. It was normal and routine for my mother to go through all four names when she wanted to call one of us (any one of us). "Jay-Lee-Mar-Allie, come get the platter down from the tall cabinet for me." It was a running family joke.
I was in high school when my parents' first grandchild was born. Some time later, I was in my parents' house, no other siblings or children were around, and my mother called me by the baby's name. Oh, did I mention he's a boy? "Matthew, come here and--uh . . ." She paused, and said, "Did I really call you Matthew?" She was somewhat disturbed--and she never did it again.
I think in her mind, Editeer= "the baby" for so long, that when there was a new "baby," she just slotted in his name in place of mine. (BTW, I laughed.)
