Replace ‘Coach’ with your little one’s name (Luna-chella) for a super cute, on trend and personalized theme. 

Must-haves: these insanely cute custom music festival wristbands for guests with your little one’s name printed on them, and obvi – these custom VIP passes, too.

Encourage your guests to get in on the fun by wearing an outfit they’d take to Coachella and hire a DJ or bust out your best playlist to mimic the atmosphere. 

First Shellebration 

Let’s shellebrate your baby girl turning one! With its pastel tones and mermaid vibes this party theme is so gorgeous you’ve got to see it!

If you love a good pun, try a party catchphrase like: oneder the sea, or let’s shellebrate! Your party is sure to make a splash!

For this party theme, think about using teal, pink and purple colors and bust out your bubble machine, seriously, babies love bubbles. This theme is also an ideal choice for a pool party.

Use lots of shell and coral accent items and feel free to go full-mermaid with everything from your decorations to your sweets. I mean, just check out how adorable these handmade custom cookies are?!

(I just threw my little guy’s third birthday and while I was *scouring* literally everywhere for cute party favors, I saw these Meri Meri seashell party favor bags, these ridiculously cute mermaid nail stickers, roll of sweet watercolor mermaid stickers, and these super pretty little sparkly seashell hair clips!)

But honestly, Meri Meri’s entire line of mermaid party decor, is seriously gorgeous – check out all pretty pieces they have!

My First Rodeo

Does this look like my first rodeo? Because it is! If you’re looking for a cute western theme for your baby girl’s 1st birthday, look no further.

A western theme is both classic and cute, it doesn’t get more fun than cow-print and a stetson right?

You can take this theme in a bunch of different directions depending on your style. Do you want to have a petting zoo for the kids and take this in a barn and farm direction? Or how about a more Southwest style with tribal prints and Mexican blankets? For a more natural take on this theme, try a cacti oasis with desert plants like succulents to tie into the decor. 

Paisley, flower crowns, hay bales, western boots and so much more. Your biggest problem if you pick this theme is going to be how to choose between all the adorable options you’ve got for decor!

Daisies

If you pick a daisy theme for your daughter’s first birthday it’s going to be bloomin’ brilliant! This delicate floral style is making a comeback in a big way.

If you think daisies are just for hippies, think again! While this trend might hit you with nostalgia for the 1970’s, a daisy-themed first birthday is so much more than that. 

Decorate with simple white daisies or try one of these super cute ‘shag’ cakes that use a grass piping tip to achieve their shaggy look.

You’ll notice these fairies all look like real little girls that have wings as opposed to a cartoonish fantasy style look. Take that into account when you’re giving notes and ideas to your decorator, and dessert creators so they know what sort of tone and style you’re aiming for.

Groovy One

If you want to continue with the book theme throughout your event, you could consider asking guests to bring board books for your one year old instead of cards with them to the party. 

Pat the bunny is a pretty simple book, so this theme is really centred around small adorable white rabbits and the illustrations from the book!
