Child welfare refers to the well-being and safety of children. It encompasses a range of services, programs, and policies that are designed to protect vulnerable young people from harm or neglect, and promote their overall healthy development. This can include providing support for families in need, preventing child abuse and neglect, finding loving homes for foster children, ensuring access to education and healthcare, and addressing issues such as poverty, homelessness, and mental illness that can impact a child's well-being. Overall, the goal of child welfare is to create safe, stable, and nurturing environments for all young people, so they can grow up happy, healthy, and thriving.
