hi, yikes hadn't thought of that!!!
However, having looked at the pic alot I don't think mum is pm!! Although adults were indeed propped, there seems no way of doing this without evidence in the pose she is in.
Suggestions for strange pose?
Hands - imagine this woman's grief, lost a child then expected to "pose" for pic, dont think i'd want to hold to close!!! (might not let go again!!)
and her face would seem to be of someone biting their lip and rolling their eyes to avoid crying (

)
hadn't thought of this aspect until someone suggest she might be pm!! sorry Maggie!
