This chapter offers a range of policy recommendations for improving child wellbeing: invest early in children’s lives; concentrate on improving the lot of vulnerable children; design interventions for children that reinforce positive development across their life cycle and across a range of well-being outcomes; create clear, achievable targets for child well-being outcomes and regularly collect high-quality information on children’s well-being that is nationally and internationally comparable. Finally, governments should continuously experiment with policies and programmes for children, rigorously evaluate them to see whether they enhance child well-being, and reallocate money from programmes that don’t work to those that do. This approach ensures resources allocated to children progressively enhance child wellbeing.
