Create a children's book cover for a story titled 'Stay Wild

Create a children's book cover for a story titled 'Stay Wild, My Child.' The central focus should be on a young girl named Joy, peacefully sleeping in her cozy bedroom. The room has purple-colored walls, filled with her belongings, including toys and books. Above her bed, the name 'Zoe is written in playful, colorful letters on the wall. The bed is comfortable with soft blankets, and nearby, there is a window with pink curtains. Outside the window, the night sky is dark with twinkling stars, showing that it is nighttime. The top half of the cover should focus on Zoe sleeping, while the bottom half should depict her dream: a bright, sunny scene where Joy is playing in a wide, grassy field with her loving mother. The dream world should feel magical, with vibrant colors and whimsical details. The title 'Stay Wild, My Child' should be placed prominently on the cover, in playful, bold letters that appeal to young readers."
