I can see it being a constant reminder. I also feel bad for her,step child or not the pain is still real for all those involved. How can u be excited about the birth of his child when your planning his funeral at the same time very bitter sweet.
My family also has some strange superstitions,things my mom & mamaw use to say or do when I was little & I find myself doing or saying them as well. Sometimes I hear other ppls superstitions & think that's crazy or it makes no sense then I realize probably about as much as mine do anyone else.
