Objectives: The goals of this study were to assess: (a) the involvement of fathers and mothers in overall and nighttime infant caregiving; (b) the links between paternal involvement in infant care and infant sleep patterns during the first 6 months.
Methods: Fifty-six couples recruited during their first pregnancy, participated in the study. After delivery (1 and 6 months), both parents completed a questionnaire assessing the involvement of fathers relative to mothers in infant caregiving. Infant sleep was assessed using actigraphy and sleep diaries.
Results: Mothers were significantly more involved than fathers in daytime and nighttime caregiving. A higher involvement of fathers in overall infant care predicted and was associated with fewer infant night-wakings and with shorter total sleep time after controlling for breastfeeding.
Conclusions: The findings highlight the importance of including fathers in developmental sleep research. Future studies should explore mechanisms underlying the relations between paternal involvement and infant sleep.
