Trajectories of change in mothers' parenting confidence and relationship with baby: a 15-month qualitative longitudinal study.

Background: Parents' experiences and their relationship to their baby undergo various changes over the course of the first year. This is particularly the case for mothers, who still tend to take on the primary caregiver role in most families in the UK. Better understanding the changes mothers experience in the first year is of importance given the impact of the parent-infant relationship for children's socio-emotional development.
