6. Rainbow Surprise Cake

Bright, cheerful, and full of color—the rainbow diaper cake makes everyone smile. Use white diapers as your “cake” base, then wrap each tier with:

  • Multi-colored ribbons
  • Rainbow baby socks and bibs tucked in
  • A rainbow plush toy as a topper

💡 Pro Tip: Color-coordinate small baby items like pacifiers or washcloths to match the rainbow palette.

Why it works: It’s unisex, vibrant, and instantly lifts the party mood.
