Birth order traits that affect personality and how you perceive yourself are in turn affected by many issues. They are gender, how you are parented to a certain extend, the adoption of another child into the family, the death of a sibling, the break-up of a marriage, the integrating of step siblings into a family unit and a role reversal which can take place occasionally, especially if the first born child is born medically or physically handicapped in some way. Another factor is a gap of more than 6 years between siblings. They have three children, then a gap of more than 6 years and then another two children who arrived much later when his wife was in her 40 s. The 4th child in the line up, will act more like a first born child due to the big age gap.
Gender affects the family dynamics as well.
A first born girl for example, followed by a first born boy and then other children, will mean the oldest boy is treated like, and exhibits many first born qualities. When selling a product or service to a first born person in business, it s helpful to remember that they are a facts and figures type of people. Show them statistical graphs and details. Middle born children are usually concerned about forming friendships with people they deal with in business, and like money back guarantees. Baby s of the family generally like pictures, glitter, and glamour.
