The Influence of Gender on Parenting Roles As noted above, couples experience many challenges upon the transition to parenthood. These challenges are often highly influenced by gender, and therefore the purpose of this section is to detail how gender influences parenting roles. Defining gender is an important first step in this examination: It is "more than an individual characteristic of females and males, and more than a role assumed by or assigned to women and men. Gender in families includes structural constraints and opportunities, beliefs and ideology, actual arrangements and activities, meanings and experiences, diversity and change, and interaction and relation" (Thompson & Walker, 1989, pp. 845-846). These aspects of how gender works in families are particularly relevant when considering issues of equality and fairness in the development of parenting roles. As has been described in the literature, couples who had relatively egalitarian relationships prior to the birth of their child typically find themselves in "traditional" roles highly influenced by stereotypical notions of gender once they become parents (Cowan & Cowan, 2000; Crohan, 1996; Fox, 2001; Hackel & Ruble, 1992; Hock, Schirtzinger, Lutz, & Widaman, 1995; Ruble et al., 1988; Steil, 1997; Thompson & Walker, 1989; Walzer, 1996). As couples' roles and experiences become more divided along these traditional gender lines, couples may feel a decreased sense of intimacy as well as decreased satisfaction in their relationship (Cowan & Cowan, 2000; Cowan et al., 1985; Hackel & Ruble, 1992; Hock et al., 1995; Lewis, 1989); past commonalities may be overshadowed by the current focus on different domains, and men and women may
