Photographing little people is perhaps the most fulfilling work that we do at Rex McDonald Studio.  In order to photograph spontaneous and natural portraits of children it becomes incumbent on us to set up a welcoming, non-threatening environment.
Children read the actions of adults and interpret them through their experiences.  If a child comes in to have their portrait made and the accompanying adult leaves their coat on, for example, many children associate that with being left at day care and separation anxiety can result.  Each action we take is important.  We've learned that we have to carefully gauge the amount of attention we give to a child during a photo session.  I encourage allowing plenty of time for a child's portrait session.  Discussing age appropriate posing and clothing ideas ahead of time is very helpful.  Infants for example, spend most of their time being held.  Perhaps they should be photographed that way as well.
Most children learn very early how to get attention, I try to set up the situation to take advantage of their efforts.  Being photographed, at its best, pictures genuine actions, reactions, expressions and mannerisms, most of which happen subconsciously.  The child must be comfortable to allow this and we set up a relaxed atmosphere to result in beautiful and satisfying photographs.
