How can we prepare for our portrait session?

Besides having your child comfortably clothed, a quick snack beforehand (as long as it doesn't get on their outfit) will help to ensure that thirst or hunger won't be a distraction.  Bringing along a comb or brush may be helpful.  Also for younger children, bringing along a favorite stuffed animal, toy or noise maker could help attract the little one's attention in the right direction.  For the older children, it may be helpful to discuss the portrait sitting with them in advance.
