Lenormand and Family Constellations

Doing a trial Grand Tableu today got me pondering significators of a sorts, especially those involved with family. We havethe core:
- Man/Woman for the client
Woman/Man for the wife/husband
-Child for your or a child
-Birds for siblinggs
and so on.

But how about larger families? What cards do we choose for individual siblings in a gt ( where you rarely laser focus on one person) to look at them individually? I have 2 children: A 9 year old and a 6 mo. Child fits well for my eldest son. But how about my baby girl? The Storks?

Others may have a different approach, but this is mine.

Most often the GT is a general focus for one person or event and describes the situations that relate to that person or event and what the influences are. if it is for the entire family and the Child fell amid some troubling cards, I would do a separate reading for each child to identify which had the problem and the description of that problem.
