Parents of children with a disability experience elevated levels of stress compared to parents of typically developing children, which represents a risk for their couple relationship. Research on families where a child has a disability is principally based on mothers. More knowledge is needed about the paternal perspective. We conducted semi-structured interviews with seven fathers (aged 36–54 years) of children with a disability (primary school age to early twenties). We analyzed the material using qualitative conventional content analysis, focusing on participants’ descriptions of couple relationships. We categorized the participants’ descriptions in two main categories: Couplehood and Co-parenting. Throughout the material, partners were described as romantic partners, co-parents, and collaborators. Participants described that couple communication and emotional expression within couples were affected by parenting a child with a disability. Moreover, participants described influence by cultural masculinity norms on their involvement as partners and parents, and on the dynamic within their couple relationships. An uneven division of labor was described. A practice implication is that communication and emotional expression styles within the parental couple should be a key focus when working with families of children with a disability. The findings also suggest more active involvement of fathers in children’s health care.
