The birth of a child is a significant change for a family, and it also signifies the beginning of a long journey of nurturing. The high-quality development of the population is reflected in the healthy growth of every individual at the micro level, and infant and toddler care has become the first step to cross the starting line. This step not only tests the cultivation of a family, but also represents a social responsibility, and its impact should not be underestimated. From a family perspective, good childcare services can alleviate the pressure of raising children, solve the problem of "no one to take care of infants and young children, and improve family happiness, thereby boosting the willingness of families to have children. From the perspective of women's development, high-quality childcare services can effectively alleviate women's worries in the workplace, promote the increase of women's employment rate, and advance gender equality and women's comprehensive development. From the perspective of population development, infancy and early childhood are the most rapidly developing periods in a person's life. Good childcare services can provide scientific and professional care and education for infants and young children, promote their physical and mental health development, and lay a solid foundation for the improvement of population quality. From the perspective of economic development, the popularization and improvement of childcare services can not only directly drive the development of the childcare industry, but also integrate related service industries, and enhance the economic vitality of society through effective integration and full utilization of resources. General Secretary Xi Jinping emphasized that high-quality population development should support Chinese style modernization, and put forward important requirements for vigorously developing a universal childcare service system. As a key component of the infant and toddler care system, childcare services play an important supporting role in achieving high-quality population development. A good childcare service system needs to have the following characteristics: firstly, universality. The series of policies and regulations related to childcare services issued by the Party and the government all regard "universal access" as the core requirement, emphasizing the wide coverage and affordability of services. This means that childcare services should be targeted towards all families, especially low - and middle-income families, providing affordable and reliable quality childcare services. The government needs to reduce operating costs and alleviate household burdens through subsidies, preferential policies, and other means. In the construction of a universal childcare service system, it is necessary to ensure fair distribution of resources and avoid significant differences between urban and rural areas, regions, and groups. The core of this value orientation is to give full play to the role of public services as a backup, achieve fair distribution of benefits for "early childhood education", and ensure equal development opportunities for young children. Secondly, professionalism. Universal childcare services should provide comprehensive and professional care and education for infants and young children, ensuring that they grow up in a safe and healthy environment. The core demands are safety and high quality. On the one hand, only safe and high-quality childcare services can create a positive childcare culture in society and promote the healthy development of the childcare service system; On the other hand, providing high-quality care for infants and young children is also an important means to help children develop and improve the quality of the population. To achieve high-quality childcare services, it is necessary to rely on a specialized talent training system, carry out interdisciplinary innovative application practices, and promote the continuous improvement of care and education concepts for childcare institutions and practitioners; At the same time, it is also necessary to establish a multi domain support system that includes healthcare, nutritional diets, mental health, etc., integrate resources, and form professional synergies; In addition, it is necessary to improve the refined management level of childcare institutions and provide operational management training for the responsible persons of childcare institutions. Again, multi stakeholder participation. Family is the primary environment for the growth of infants and young children, and parents are the first responsible persons for caring for infants and young children. Therefore, the construction of a universal childcare service system should encourage families to actively participate and provide parents with scientific guidance and support for parenting. As the most direct force supporting family upbringing, the community should fully utilize its own resources and platforms, and actively participate in childcare services. As a fundamental unit of urban public services and governance, community childcare helps to achieve "co construction, co governance, and sharing" and explore diverse forms of community childcare; Pay attention to the mutual assistance resources among neighbors in the community, make full use of other service projects in the community, and achieve resource sharing; It is also convenient to develop childcare services with local characteristics based on local conditions. In addition, employers can also play an important role in providing childcare services. Encouraging and supporting qualified employers to provide childcare services is not only conducive to ensuring the labor participation of female family members and other family caregivers, which is in line with China's employment priority strategy, but also demonstrates the corporate social responsibility of employers, helps promote the interests and welfare of employees' families, and enhances the attractiveness of employers. Finally, sustainability. The construction of a universal childcare service system should consider its long-term sustainability. This includes funding support for the service system, talent development, and improvement of policies and regulations. In terms of financial security, the government should establish a normalized fiscal budget and investment mechanism, continuously stabilize fiscal investment, and encourage social forces to participate, forming diversified funding sources. In terms of talent team building, we will strengthen cooperation between universities, vocational colleges, and childcare service institutions, establish majors related to childcare services, improve the training program for infant and toddler care talents, cultivate high-quality professionals, and provide talent guarantees for the long-term development of the service system. Establish a professional title system for childcare talents, facilitate their career development path, and provide corresponding incentive mechanisms. This will help enhance the professional identity and sense of belonging of practitioners, and promote the healthy development of the talent pool. In terms of policies and regulations, the government needs to accelerate the improvement of relevant laws and regulations such as the Regulations on Infant and Child Care Services, clarify the positioning, standards, and supervision of childcare services, and provide legal protection for the development of the industry. Industry associations also need to develop industry standards and behavioral norms, establish the values and concepts of childcare services, guide industry management, and form industry self-discipline. At present, the construction of China's childcare service system still faces multiple challenges such as prominent supply-demand contradictions, uneven service quality, shortage of professional talents, and insufficient policy funding. However, driven by the interrelated and mutually reinforcing core concepts and principles of inclusiveness, professionalism, multi stakeholder participation, and sustainability, encouraging more social forces to participate, explore, and pilot will continue to promote the high-quality development of childcare services, and thus promote the high-quality development of the population.
