Their childhood and adolescence can be compared to that of the winter solstice. Theirs is the shortest childhoods of all birth orders. Being the oldest child in the family can be a burdensome experience. They must be perfect or near perfect. They cannot be children nor adolescence in the normative sense.
Their parents do not spend much time with them nor give them individualized attention because they are viewed as adults and thus can take care of themselves.
