(1) Background: This study aims to explore children's social information processing (SIP) as an explanatory mechanism in the link between parent-child relationship and children's learning difficulties in kindergarten; (2) Methods: The sample included 115 kindergarteners (62 girls; 53 boys; Mage = 68.5 months, SD = 6.04), their parents and the school teacher. Parents reported on relationship quality with the child and teachers reported on children's learning difficulties and school achievements. Children's SIP was assessed with the social information processing interview-preschool version (3) Results: Mother and father relationship quality with the child associated with children's SIP; however, only the father's but not the mother's quality of relationship with the child was associated with children's learning difficulties and school achievements. Children's SIP mediated this latter link; (4) Conclusions: Parents' relationship quality with the child and children's SIP are pertinent factors in children's learning in the early years. The father-child relationship seems to be a strong determinant of a child's approach to learning and achievement and may have long lasting effects on children's mental health.
