A new generation of men are redefining fatherhood and masculinity.

According to census figures, one in four dads takes care of his preschooler during the time the mother is working. The number of children who are raised by a primary-care father is more than 2 million and rising. And fathers who work full time are more involved in their children's lives. According to the Families and Work Institute in New York City, dads now provide up to three-fourths of the child care mothers do, up from one-half 30 years ago.

A father's presence makes a big difference in a child's long-term development, say psychologists at the University of California, Riverside. Children with involved dads regulate their own emotions better. They have better social skills, and more success in school.

A father's influence comes through the unique ways they play and interact with kids. Kids who interact with their fathers are more likely to tolerate frustration and master tasks on their own before asking for help.

Quoted in Psychology Today, psychologists at the University of Connecticut say a father's love may be the best gift he can give. Their 40-year study shows it to be a significant buffer against depression and conduct problems.

There is already a mountain of research showing that kids without a father in the picture are at a higher risk for school dropout, drug use, teen pregnancy, delinquency, and suicide.

To all of our fathers, we say, "Thanks Dad," your love and caring are important factors in bringing the next generation successfully into adulthood.
