Abstract: Child healthcare，which is concerned with the normative patterns of child growth and development and their influencing factors，has attracted increasing attention in recent years. This article provides a systematic review of the latest advances in the early assessment of childhood nutrition and growth status，pediatric nutrition and feeding practices，and other related fields.  Currently，China's demographic structure is characterized by low birth rate，low mortality，high aging，and high life expectancy，and children have been recognized as a strategic resource for sustainable national development. Heightened societal expectations regarding children's growth，health，developmental potential and quality of life have，therefore，created significant opportunities for the advancement of the child healthcare discipline. This article proposes developing an integrated child healthcare system that spans the entire life course and encompasses the full continuum of care，forming a functionally comprehensive child health service chain. It is emphasized that in the new era，child healthcare should take the promotion of child development as its central objective. Achieving this goal requires robust multidisciplinary collaboration in the medical field，strengthened interdisciplinary integration with educational science，psychology，sociology，and related disciplines，and enhanced intersectoral coordination with sectors such as education，civil affairs，and women’s organizations. By fostering an optimal environment for nurturing and care，this integrated approach aims to promote early childhood development and maximize children’s developmental potential，ultimately achieving the strategic goal of enhancing overall population quality and aiding the country’s long-term development.
