Like the way you carry a child who is asleep ?
No. The way he stood, tilted his head, what he looked like, any striking features, etc is what a photofit concentrated on and not the way he carried the child. If you insist on the "carry a child" angle 9excuse the pun)then lets explore it shall we?
To be able to compare or draw a comparison to others and be able to identify a person by the way he/she carried a child one would have to have a community who regularly carry their children around. If no one carries their children around then there is nothing to 'use' or observe to compare to. Everyone carrying their children around carry them in different ways for different situations. Should the child the man in the photofit have been Madeleine, then it was generally accepted she was either sleeping or drugged. Sleeping children are generally carried in another way i.e. over the shoulder (but not always exclusively). If everyone followed your rule - carried their children in exactly the same way as the man in the photofit then you can use the method or way of carrying the child as a factor in the photofit for the public to look out for/use to identify the person. But that is not what the photofit concentrated on.
The angle at which the child was carried is of little relevance unless you have everyone in the world carrying their children around so that one has something to compare the photofit to.
A possible suspect is able to change the way he carries a child because it has been made public, making the importance of the angle carried in the photofit invalid, BUT he can't change his facial features.
Therefore the angle at which the child was carried is irrelevant. What is relevant and of importance is the way the person looked and any feature like a body posture that will trigger the memory of someone who might have seen him.
Capiche!
