you have to turn it into a positive,
try to see this physical beacon, as a maker, you can think each time you notice this child,
hey my ......... would be that age now, that is where my gap is,
you are allowed for it to feel as if there is a hole, it's terrible hard to be a parent to a dead child,
when I look at my friends beautiful daughter born at the same time as my son(died later on) , I get a slight pang, I can see where his place was,
her daughter is often in the same classes as my two younger children, who probable wouldn't be here if their older brother hadn't died,
It never goes away, but it does change into something special and positive.
