The purpose of this study was to look into caregiving predictors of maternal sleep problems and early childhood behavioural and cognitive outcomes.
Latent growth curve modeling revealed that maternal reported sleep problems decreased in children between the ages of 18 and 84 months, and that harsh-intrusive parenting at six months predicted sleep problems at 18 months. Maternal reported sleep problems at 18 months predicted aggressive behaviors in kindergarten and second grade.
The study concluded that parenting at the age of six months has an impact on sleep quality at the age of eighteen months, which is linked to aggressive behaviour in early childhood.
