"Rough and tumble play between fathers and their young children is part of their development, shaping their children's brain so that their children develop the ability to manage emotions and thinking and physical action altogether," said Fletcher. "This is a key developmental stage for children in that preschool area between the ages of about two and a half and five. That's when children learn to put all those things together."

The researchers believe that the most important aspect of this play is that it gives children a sense of achievement when they 'defeat' a more powerful adult, building their self-confidence and concentration. However, fathers who resist their children, can also teach them the life lesson that, in life, you don't always win. The act of a stronger adult holding back that strength also helps to build trust between father and child.
These kinds of lessons can be crucial in child developmental stages as they begin to build their outlook on the world. "We think it has implications for children's resilience. So, if parents want their children to grow up and not get into drugs and not get into trouble, if they want them to do well academically, than this is probably a good thing to do," said Fletcher. "We did find a correlation so that the dad's whose play was much better coordinated according to our measures, those children had less problems."
