Third Birthday Party Themes

Your tiny tornado is saying “tata” to two, and it’s time to party! Third birthdays are so fun because your child at this point truly understands what a birthday is, and that everyone there is celebrating them. Now all you have to do is pick a theme and get to planning.

Any character or theme your little one loves is fair game, but we’ve assembled some favourites in case you’re stuck. Whichever direction you go from sea creatures to dinosaurs and sweets to the seventies, just make sure you keep the decorations and treats in their favourite colours—and always add lots of balloons.

Three is really an easy age to “wow” them; just keep the decor cute and the sweets abundant and you’ll have a happy pack of 3-year-olds making memories (and noise!). These are some of our favourite 3-year-old birthday party ideas!

What we love about this wording is it can apply to whatever makes your little one “wild.” This execution is on the boho side, but you can also take “Young, Wild, and Three” to the jungle or turn it into a colourful dance party.
