Can you even believe that your baby is almost ONE?!

Getting to the 1-year mark is a momentous occasion, and definitely one to be celebrated – not only to shine a light on your sweet babe for hitting a new milestone, but for YOU for surviving that first year!

Throwing a fun 1st birthday party for your little girl or boy is a wonderful way to celebrate with friends and family, and although they won’t remember it…you sure will!

Choosing the theme for baby’s first birthday party can be a hard decision, especially if you don’t want to go with the more traditional ideas of princesses and trucks.

Luckily, that’s where we come in.

We’ve rounded up some of the most unique and creative ideas for a 1st birthday party, with themes that are baby-friendly, but also fun for grown-up guests. These party ideas include themes with a play-on-words of “one” and “first”, plus more unique ways to celebrate for both girls and boys. And we’ve included lots of inspiration images to give you ideas for food, cake, venue, supplies and more!

So whether you want to host a backyard bash, or will be stuck inside in the winter, you’ll have no problem finding the perfect 1st birthday party theme for your big 1-year old!

And remember, take lots of photos and videos – because they won’t remember the big day when they’re older, they can still have memories of it.
