A Community-enabled Readiness for first 1000 Days Learning Ecosystem (CRADLE) for first-time families: study protocol of a three-arm randomised controlled trial.

Background: Enhanced parenting self-efficacy (PSE) contributes to positive parenting and future parental-child health. First-time parents, in particular, are in need of support since the pregnancy until post-delivery to strengthen their early PSE. However, there is a lack of effective and sustainable relevant programmes in the community.
