During the teen years and later, a girl who has not had a rewarding relationship with her father is apt to feel insecure around males. She may feel unattractive as a woman, doubt that any man could love her for herself, and distrust men in general. Richard Warshack, The Custody Revolution , p. 44 - 45. Even at five months, boys who have more contact with their father are more sociable with a stranger. Richard Warshack, The Custody Revolution , p. 41.
Fathers do more physical play.
A lot of physical father play corresponds to better, deeper friendships with peers among children. Children learn self-control, how to manage and express their emotions and recognize others' cues. Girls whose fathers play with them a lot tend to be more popular with peers and more assertive in their interpersonal relationships throughout their lives. Men and women who had warm paternal relationships have better, longer marriages and engage in more recreation. The best predictor of empathy in adult men and women is the amount of time with their father while growing up.
