The parental investment theory predicts decreased investment when the child has low reproductive potential and parental resources are scarce. In this context, caring for children with disabilities may pose a dilemma for parents. This study investigated the relationships between family and environmental unpredictability during parents’ childhood and parental investment during adulthood for children with disabilities. This is a descriptive, cross-sectional, and quantitative study. Family members of 124 children with disabilities answered the Socioeconomic Questionnaire, the Brazilian Economic Classification Criterion, the Childhood Environmental Unpredictability Questionnaire, the Scale of Family Unpredictability during Childhood (EIFI, acronym in Portuguese), and the Parental Investment Scale (EIP, acronym in Portuguese). The results indicate that, in general, children with disabilities received high levels of parental investment, possibly due to the socioeconomic characteristics of the sample. Greater environmental unpredictability during parents’ childhood was associated with lower childcare investment, along with the influence of the type of disability and the child’s sex. No correlations were found between the EIFI and the EIP.
