This study examined the correlates of fathers’ satisfaction with physical affection (SPA) in their marital relationship before and after the birth of a new baby. Both parents ( N = 97) completed surveys assessing SPA, and fathers completed surveys assessing division of household labor and coparenting quality during the third trimester of pregnancy and again at 3 months post-birth. An actor-partner interdependence model revealed partner effects, such that mothers’ SPA post-birth was predicted by fathers’ SPA pre-birth but not viceversa. Cross-lagged path analyses indicated that fathers who have high SPA pre-birth reported more supportive coparenting post-birth. Furthermore, fathers who believed pre-birth that they would be more involved in child-related household labor had increased SPA after the birth of a new baby. Results are discussed in terms of implications for couple and family therapy, education for new fathers, as well as programs designed to support parents during the transition to parenthood.
