Background: Sleep regulation and consolidation represent critical developmental processes that occur in the first years of life. Recent studies have highlighted the contribution of caregivers to sleep development. However, the majority of them have primarily focused on maternal behaviors, overlooking fathers. The main goal of the present study was to investigate the associations between paternal and maternal involvement in children's sleep care and the number of night awakenings reported by both parents in infants and toddlers.
Methods: One-hundred-and-one families of infants aged 8 to 12 months and 54 families of toddlers aged 18 to 36 months filled out the following self-report questionnaires: The Brief Infant Sleep Questionnaire and an ad hoc questionnaire to assess parental involvement in sleep care for children. A moderate actor-partner interdependence (APIM) with path analysis was performed to test the predictive role of parental involvement on the children's sleep (no. of nocturnal awakenings) and the moderation role of age on these relationships.
Results: Paternal involvement in children's sleep care was associated with the number of night awakenings reported by both parents. Moreover, a significant interaction effect emerged between the children's age and paternal involvement in children's sleep care for predicting nocturnal awakenings.
Conclusions: The main outcomes of this study point to the protective role of paternal involvement in children's sleep during the first years of life.
