Being a parent is extremely demanding both physically and psychologically, particularly during the early childhood, when child socio-emotional development is crucial. The parental role is all the more difficult today because of the growing demands of the labour market, the increasing instability of conjugal unions and the complexity of the resulting reconstituted families.
This paper describes the evolution of certain parental perceptions and behaviours, specifically, parental self-efficacy, the perception of parental impact, parental coercive behaviours and parental overprotection, as self-reported in the 1998, 1999 and 2000 rounds of the Québec Longitudinal Study of Child Development (QLSCD 1998-2000), when the children were aged 5, 17 and 29 months. First, it describes the general evolution of the parent's profiles for all biological mothers and fathers. It then compares mothers and fathers in households where both parents are present. Finally, it examines individual differences in developmental trajectories of coercive behaviours for both mothers and fathers.
