One way children seek more attention from parents is by making themselves different from their siblings, particularly if they are close in age. Researchers have found that the first two children in a family are typically more different from each other than the second and third. Girls with brothers show their differences to a maximum degree by being morefeminine than girls with sisters. A 2003 research paper studied adolescents from 185 families over two years, finding that those who changed to make themselves different from their siblings were successful in increasing the amount of warmth they gained from their parents.
