Seb is such as calm, pleasant and contented little baby, he follows with warm and shining eyes any adult in his vicinity, and to give him attention is to recieve a huge smile of afirmation. It is as if any attention he has is a bonus, as he grows up in the shadow of his older brother. It makes you think about 'number two' child and the differences with 'number one'.
Though my father maintains that according to psychology, only being first born has any predictive power in life outcomes. Nevertheless, at the dinner table, birth order is a recurrent theme, and not solely due to positions taken out of vested interests (number twos are so stable and well adjusted), regardless of who is at dinner, the subject never fails to generate enthusiasm. I'm sometimes struck that there seem to be no special words in English for second or third born; perhaps there are.
