In the present pilot study the feasibility and efficacy of Baby Triple P- an antenatal parent training- are investigated. Healthy becoming first time parents were randomly allocated to either the Baby Triple P parent-training group or a care as usual control group. It is expected that 78 couples of becoming first time parents are recruited. It is hypothesized that parents and their infants in the parent training group will show significantly less psychopathology / regulation problems and better partnership quality than participants in the control condition.
