    The Surprising Benefits of Letting Kids Play in Dirt and Mud

    While good hygiene is important, so is getting dirty sometimes!

    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! 

    Young, Wild, and Three

    [object Object]

    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. 

    Tea for Three Birthday Party

    [object Object]

    Photo: The Pink Dream

    A charming little tea party is easy to pull off and the stuff little girls’ dreams are made of. Highlight any of her favourite colours, and you can use mismatched vintage linens and cups from the thrift store if you’d like the “real thing” without risking damage to Grandma’s stuff. 

    A Three-Ring Circus Third Birthday Theme

    Photo: PartyLovin.com

    Circus-theme birthdays can be simple or complex; the important elements are tickets for entry, pockets of popcorn, and bright colours as far as the eye can see.

    Yippee! I’m Three Birthday Party

    Pull together all their favourite things right now (from unicorns to bugs) with an open-ended party theme that’ll be just as fun to plan as it is to attend.

    “Three-I-E-I-O” Third Birthday Party

    From mermaids and narwhals to great white sharks, combine your tot’s favourite ocean creatures with shells and sand for a sensational sea-themed party they’ll adore. Pro Tip: Use clear balloons in small clusters as “bubbles” and twist green streamers to emulate seaweed.

    The beloved gang from this classic show will charm your mini muppet and all their buddies. For added fun, create fruit plates that look like their favourite characters, using cut-up bananas for Big Bird, red berries for Elmo, and so on.

    If your mini royalty can’t narrow it down to just one, a three-princess soiree is even better! Princess parties are easy to pull off with readily available decor in every colour palette from pastel to brights. 

    Threenager Third Birthday Party

    It’s another open-ended theme that can highlight what they’re like at three. If you’re celebrating a sassy little fashion-lover, highlight that with all their favourite things. If your threenager is car- or sports-obsessed, that works, too. The “threenager” party can also just be very old school; primary colours, balloons, music and dancing, and a simple cake. Voila!
