This study examined the association between supportive and adverse aspects of the child–parent relationship in childhood (parental understanding and exposure to parental physical abuse, respectively) and providing care to a parent with health limitations among middle-aged and older adults. It explores whether these associations vary across broad macro-geographical regions, through the prism of the Informal Care Model. Data were drawn from the Survey of Health, Ageing and Retirement in Europe (SHARE), Waves 7 and 9. The subsamples comprised respondents aged 50 years and older, 2,970 with an unhealthy mother and 890 with an unhealthy father. The degree of maternal understanding in childhood was positively associated with providing care to a mother, but not to a father. Frequency of parental physical abuse (for mothers and fathers) was unrelated to providing care. Interaction analyses indicated regional variations in associations between maternal physical abuse and providing care to mothers, and between paternal understanding and providing care to fathers. Taken together, providing care was more strongly associated with childhood relationship characteristics in regions typically characterized by more established long-term care policies and weaker familistic norms. The findings underscore the need to support adult children care-givers, particularly those who perceived their childhood relationship with their parent as negative. Support efforts may be especially important in contexts where care-giving relies more heavily on family resources and formal long-term care is more limited. Further research should focus on differences in the mechanisms linking early parent–child relationships to care-giving for mothers versus fathers.
