The couvade syndrome and side preference in child holding.

In a prospective study of expectant couples 20% of the men suffered from the couvade syndrome. About 80% of both women and men hold their newborn infant to the left and 20% to the right, irrespective of handedness. Compared with others, men with the syndrome more frequently developed a right-side preference in child holding. Right-holding men more often had sons than daughters. Right-holders with the couvade syndrome were more often attached to and more closely identified with their mothers than were right-holding non-sufferers.
