SEASONAL FIRST BIRTHDAY PARTY

  • Little Pumpkin
  • Winter One-derland
  • Lucky One (St. Patrick’s Day)
  • Farmer’s Market
  • Beach Party (think lots of bright colors!)

The season your baby’s first birthday party will fall in can play a big part in choosing a theme! Whether it is in the summer or winter, you can choose a party theme to coordinate. For example, you might throw a “Little Pumpkin” party in the fall. In March, a “Lucky One” party would be absolutely adorable for a birthday around St. Patrick’s Day. You could carry the same theme to future parties from year to year.

Having a birthday party in the coldest part of winter? Embrace the snow and ice with a Winter ONEderland 1st birthday party. Use lots of muted blues or pinks paired with pretty metallics. Or go with bright colors to contrast the season! Create a hot cocoa bar instead of a cake table to keep all your guests feeling warm and toasty.

How to Pick a First Birthday Theme?

Picking a first birthday party theme can take time, considering the millions of options available, just some of which we’ve listed above. So how do you choose? Here are some questions to answer that might inspire the perfect theme for your baby’s first birthday party:

  • What’s your favorite book to read with your baby? A book you remember from your childhood that you now read to your baby can make a very creative theme!
  • What color do you like to dress your baby in most? If your baby looks good in blue and you tend to dress him accordingly, an ocean or shark theme makes sense – complete with blue balloons. A princess party theme may suit you if you tend to dress your little girl in dreamy pastels.
  • What season was your baby born in? Some great ideas can come from thinking about the season your baby’s first birthday will fall in. Palm trees provide a perfect backdrop for a summer party theme. Or think of hay bales and pumpkins for a fun fall birthday theme.
  • What childhood characters or icons are important to you? Perhaps you were a big fan of Sesame Street as a child. Throwing a party full of primary colors and some of your favorite characters would be fun. Think back to your own childhood for first birthday party ideas.
  • What are your family interests? (i.e., nature, sports, music) What does your family like to do together, or what are you looking forward to doing as your birthday boy or birthday girl grows up? These questions could spark a fabulous first birthday party theme unique to your family.

Tips for Your First Birthday Party

We have a fantastic and practical guide to throwing your baby’s first birthday party. Here are a few of our favorite tips for throwing your big bash:

  1. Choose the time wisely: The birthday party should only last an hour to an hour-and-a-half because babies are known for short attention spans and lose interest quickly. Host the party either late morning or late afternoon – before or after baby’s nap – never during nap time!
  2. Create a menu that works for everyone: Are there any food allergies to consider? Keep snacks simple and kid-friendly. Cut-up fruit and graham crackers are suitable for kids. Any sweet treats on the dessert table should follow the same guidelines.

Make sure to pick a first birthday theme that you love this year because once your baby isn’t a baby anymore, you won’t have as much of a say in future birthday party themes!
