Best First Birthday Themes

1. Peppa Pig Birthday Party

unique first birthday themes girl

Peppa Pig is an adorable and a super easy theme to recreate! This was a small birthday party that we did for our daughter! Although it was just her and one other baby, I still wanted to make a cute birthday that she could look back on for pictures! This birthday set up was under $100!

To recreate this look, you need this fun bounce house! This bounce house is the perfect size for 1–3-year-olds! This was small enough to tuck away in a corner and they had an absolute blast climbing inside of it! If you want an outdoor birthday, you can also use it outdoors as well!

*Disclaimer your child will love this bounce house, and you will have it blown up in your house for days to come!

Now for the decorations we suggest using this balloon arch with a kit! Pastel colors look beautiful with Peppa and her whole family. This balloon arch kit is $11 and comes with everything that you needed to create this beautiful arch! All you need is some extra tape (we used painters tape) to help secure it to your wall without damaging your paint! Since the kit comes with a lot of balloons, you can blow some extras to decorate throughout your house.

To complete the look, you need Peppa Pig balloons! We blew them up and taped them on the bounce house! Since the balloons are pretty big, she was so excited to see Peppa was almost the same size as her! Secure these balloons with tape throughout to bring the look all together!

Top this off with a happy birthday banner and you can get a small cake or cupcake to sing happy birthday to your little one! For food we decided on some homemade pasta for the adults. This theme is perfect for smaller parties and very budget friendly!

2. One Happy Dude

One happy dude is a super cute retro look for a first birthday party! This simple birthday theme is perfect for simple birthday parties and one of our favorites! All you need is some black and yellow balloons for an arch and a cute birthday banner! You can get an entire birthday decorating kit from amazon for under $30!

4. Construction Theme Birthday Party

We threw my son a construction themed birthday party for his first birthday! He loved playing with dirt and playing with construction vehicles, so this was right up his alley! Since we had a ton of kids invited for this party, we made sure to get a kids table! In this table we did arts and crafts! They also ate here and made a mess which was perfectly fine and easy to clean up!

We used the bounce house that we had purchased previously from our daughters Peppa’s theme birthday party (linked above). We also purchased a larger bounce house for the bigger kids! This is something we have reused every year until today! This was an investment but worth every penny! Definitely beats the price for just renting a bounce house for one day!

Like the other themes, we also used a balloon arch kit for our DIY balloon arch! We outlined our banner with balloons and secured it the best we could for a windy day! We recommend using command hooks and securing them to your house with painters’ tape. From there, you can tie your balloon arch with a string, and it will not move.

This party was a little bit pricier since we bought the large bounce house but other than that, the decorations were fairly inexpensive! We got a construction cake as well as some little treats for a treat table. As for food, we catered some food from our local restaurant!
