"Design a series of background mock-ups for a prenatal theme

"Design a series of background mock-ups for a prenatal theme, suitable for use in a baby book or prenatal journal. Each background should evoke a sense of warmth and calmness, featuring soft pastel colors. Include subtle, delicate elements such as fluffy clouds, gentle waves, or floral patterns to symbolize growth and new beginnings. Add tiny, charming details like baby footprints, pacifiers, or tiny hearts scattered across the page. Ensure the designs are gentle and soothing, with soft gradients and smooth edges, creating a peaceful and nurturing atmosphere."
