Each idea can be customized to your style, and if it's hyperlinked - don't miss the full guide with vendor suggestions, décor inspo., and more!

Baby Shower Themes

  • Storybook Baby Shower: Guests brought books instead of cards, and gifts weren’t wrapped, giving me more time to mingle. “If You Give a Mouse a Cookie” sat by a pile of chocolate chip cookies, “The Very Hungry Caterpillar” inspired the fruit tray, and “Peter Rabbit” paired perfectly with veggies.
  • Taco ’Bout a Baby: A colorful fiesta with tacos, bright decorations, and a whole lot of fun.
  • Born to Be Wild: A Twin Baby Shower Adventure: Celebrate double the joy with a safari-inspired shower featuring wild animal décor, earthy tones, and playful jungle details—perfect for welcoming twin boys on their next big adventure.
  • A Little Cutie Is on the Way: Sweet citrus vibes with orange-themed décor and fresh details.
  • Sweet Baby Girl Soirée: A chic celebration in shades of pink, mauve, and gold with delicate banners, soft florals, and a touch of sparkle.
  • Tiny Human Shindig: Instead of a traditional shower, we hosted a come-and-go "sip and see" gathering so friends and family could meet our newest addition all at once ... no endless scheduling texts required!

  • First Trip Around the Sun: A galaxy-inspired party that’s out of this world for the big ONE.
  • Willow in ONEderland: A whimsical Alice in Wonderland–themed bash, complete with life-sized cutouts of Alice and the Mad Hatter, plus teacups and playing cards for simple décor.
