Play in the early years of life has a profound and long-lasting impact on a child's health, well-being, and long-term development. Studies have shown that early play experiences improve a child's physical growth, their capacity for learning, chances of finishing school, future employability, and personal income. Disadvantaged children have been disproportionately affected by the pandemic with children living in poverty having fewer opportunities to play safely. Indeed, recent research identified the extra costs involved in having children at home for longer without access to vital free services, requiring increased spending on food, heating, and occupying children indoors. For many children in vulnerable families, the pandemic restrictions have impacted every part of their life including nutrition, education and play having an adverse effect on their physical and mental wellbeing. #SummerOfPlay aims to give children the space, time, and freedom to play this summer as lockdown eases.
