How do you think they get child models just set and look sweet for a photographer? Do you think that they are bribed and with what? Really how were they trained. Maybe they don't ever photograph with their siblings. Maybe the photographer has someone else assisting, place the child, think of details in the shoot, do the lighting. Someday I will have a trained and paid assistant to do all this for me. Than my unpaid helpless husband can get back to his life.
