The Ultimate List of First Birthday Theme Ideas

40 First Birthday Theme Ideas For An Unforgettable Celebration

Looking for a first birthday party theme? But not sure where to even start? Take a look through this list of 40 on trend theme ideas to help you plan your baby’s 1st birthday in style.

It’s such an exciting time, your little baby is turning the big ONE and you want to celebrate their first birthday (and surviving the first year of parenting) in style!! But how do you choose a first birthday theme?

Start with your child’s interests, is there a particular item they love or shows an interest in? A favourite toy, an animal,  or tv show? You could incorporate this as part of their 1st birthday theme. If they don’t have one thing they particularly love, you could take the opportunity to choose something YOU love. This maybe the only birthday for a few years that you will be able to freely choose the theme (without them being able to dig their heels in!) so you can choose a first birthday theme that is something age appropriate you love.

Otherwise you can also use a set colour pallet instead of using a set birthday party theme. Choose some complimentary colours such as; rose gold, shades of blue, pink and gold, pastel, or bright.

Lets take a look at some first birthday theme ideas for some more inspiration for you;


Sweet One (Lollies/Icecream) – All things sweet; lollies, icecream, chocolate bars, lollypops, doughnuts, cupcakes. Use pastel or bright  colours to make it all the sweetness pop!
