Happy happy birthday to your little one! Here at Celebration Wishes, we know the joy and mixed emotions that can come with your baby reaching new milestones. That said, celebrating the first year of laughter, tears, and incredible growth during their 1st birthday party will make for a beautiful core memory.

Whether you want a small gathering alongside family to ring in their next year or if you opt to throw a Kardashian-style bash, choosing a theme can feel like a big deal. We’ve got you covered with the birthday themes, so you can focus on celebrating this happy day!

1st Birthday Party Ideas

1. Wizard of Oz

Lions and tigers and BABIES, oh my! Yep, you guessed it.We’re kicking off our party themes with a Hollywood classic! Make your own yellow brick road and dress your baby as one of the infamous characters, like the lion or Glinda the Good Witch.

Get hands-on and make some background decor inspired by Oz, using cardboard boxes, paint, and a whole lot of glitter! Order a cake shaped like ruby red slippers and put mini bottles of bubbles in your goodie bags! Transforming your party space into the immersive world of Oz will keep young party goers entertained and leave guests exclaiming, “we’re not in Kansas anymore!”

Food Idea: Yellow brick road cheese board

Drink Idea: Green glitter Oz-mopolitan cocktail

2. Bee-autiful Day

A bumblebee themed birthday party lends itself to bright colorful decor. Hang yellow balloons and streamers and fill the room with sunflowers. Making the space feel on theme will be easy, just source plates, cups, paper florals and anything else you can find in yellow and black!

Hang a bumble-bee pinata for any older kids (or even parents) in attendance, and head to Pinterest to find honey-flavored recipes to incorporate into the day. Hiring a sugar cookie artist to make bumblebee cookies can be great favors for your guests, both kids and grown-ups alike!

A Baby Party, but Mostly for You

Let’s face it – while this party is all about celebrating the first year of your baby’s life, it’s also about celebrating you and all of the challenges and sleepless nights you’ve overcome while adjusting to your new normal.

We hope these party ideas encourage you to make more special memories with your baby, while toasting all of the amazing highs and tearful moments that got you to this happy day. Invite your friends, family, and loved ones to share fruity drinks and good laughs, and know that you’ve done a great job. Cheers to many more happy celebrations ahead!

Consider setting up an online registry for yourself (or setting one up for the parents) and contribute to a relaxing overnight spa getaway for them. The parents have had a rewarding but exhausting year and they deserve to get pampered!
