Newborns all have the same nose. Mothers probably know this is not true, but it seems to me that every tiny baby has the same tiny button of a nose and that not until somewhere between the ages of one and two do individual baby noses begin to be visibly differentiated. It happens about the same time babies get interested in talking. Those two things together (the new nose shape and spoken language) make for more of an individuated personality.This is my personal theory of child development based on close observation of very few examples, mainly just the one example of Mabel Watson Payne plus much vaguer and more distant memories of my daughter, her mother..
