55+ Cute & Spooky Costumes For Infants, Toddlers, And Children

Infant Halloween Onesie

Whether your sim is taking their Infant out for their first Halloween or staying home to give out candy, their babies will look seasonably appropriate and endlessly cute in one of these fun Halloween-print onesies.

Infant Halloween Romper

Take the neighborhood by storm when you take your Infant Trick-or-Treating in this festive romper. It’s a great option for babes in warmer neighborhoods who want to dress seasonally without sweating!

Baby Witch

A small set of conversions so your Infant can become the cutest witch in the coven. While the dress & hair are base game compatible, the hat requires Spooky Stuff.

The dress would be great for a tiny Wednesday costume, too!

Cute Ghost Outfit

The idea of an Infant ghost is pretty fun because it’s one of the few costumes they could come up with on their own. Just watch your babe pull a blanket over their head and you have an instant costume! They can match their older siblings, too!

Pumpkin Costume

This outfit just tickles us. It’s a great costume for Spooky season or Harvestfest, but the idea of a little Infant trying to get around with a giant pumpkin surrounding them is pretty amusing! This one might be best saved for photoshoots.

Little Pumpkin

Here’s a cute and festive costume for your Infant sims that will have them bringing home the ribbon for best Jack-‘o-lantern without being an actual pumpkin!

Strawberry

Something about Infants dressed as food will make all but the grouchiest sims crack a smile. And with strawberry season stretching over several months, there’s no bad time to put your Infant in this outfit!

Flounder

Whether “The Little Mermaid” is your tot’s favorite animated movie or they just really like fishies, they’ll be precious in this outfit!

Wild Onesie

Simmer strawberrylattesims converted this Toddler onesie from the Werewolves SP so your littlest cubs can wear it, too. And this one is base game compatible!

Wild And Cute

AH SO CUTE!!!!! We cannot pick a favorite from this adorable trio because they are all too precious to handle!

Halloween Conversions For Infants

Horns, wings, and tails, oh my! This is a collection of conversions from other simmers, made for Infants. Use them for holiday costumes, or give your Occult babes a more appropriate look for their species.

You will need to download the original CC for the conversions to work, but everything you need is linked in the post.

Crayons Costume

Here are crayons you don’t have to worry about your Toddler eating! Dress them in their favorite color, or do a group costume with the whole Daycare class. So cute!

Halloween Pumpkin Hat

A great option for Toddlers who refuse to wear a costume (or clothing at all), allowing your sims to get festive at the drop of a hat!

Narvi Costume

Dress your kiddos like plump pumpkins, juicy strawberries, and budding flowers with this cute outfit. Wear it for the spooky holiday or don it at the farmer’s market or Finchwick fair!

My Lil’ Pumpkin

This adorable gourd-shaped garment works as a Halloween costume or a festive outfit for any time of the year! Your tots can dress up as a pumpkin, jack-‘o-lantern, avocado, aubergine, acorn, and more! The round shape is incredibly adorable on our chubby little ones.

Little Fairy Wings

Whether you’re after a little embellishment on your Toddler’s Trick-or-Treat look or playing a Household full of fairies, these wings will quickly become your new favorite.

Bugabee Costume

A sweet little onesie that comes in 4 colorways, each very different from the others which makes it a really versatile outfit for your tots’ wardrobe. We can’t think of a bad time to wear it!

Spider Costume

Even the biggest arachnophobe will find it difficult being scared of such a silly spider! Granted, the costume only has 6 legs so it’s technically not a spider anyway, but regardless, it’s so cute! You can find additional color swatches for this costume here.

Mickey Costume

Become the most well-known cartoon character of all time with this precious 4-piece set, available in multiple swatches if red isn’t your thing. The hat is perfect theme park attire, too!

Cat Set

Each piece from this collection is a standalone item so you can mix & match to create the perfect look for your Toddler! Most of the items can double as pieces for other animals which makes it a versatile set to have.

Cat Costume

What a cute costume! We love all the details—the whiskers, special red eyes for the black kitty swatch, and that tail! This is one your Toddler might not ever want to take off.

Sheep Costume

A perfect outfit for Trick-or-Treat, Easter, or just ushering in the springtime. Be careful not to put too many tots in this look at once; if your sim has to count how many are running around they might just fall asleep!

Dinosaur Onesie

The perfect outfit for stomping over a city made of toy blocks or digging in the sandbox! There’s also a version available without the hood.

Peter Pan Outfit

Channel your Toddler’s forever-inner-child with this super cute Peter Pan costume. We love the details such as the feather in the hat and the belt scabbard! With a little imagination, this outfit could double as a costume for Legend of Zelda’s Link.

Superhero Onesies and Masks

Here’s a simple themed onesie and optional mask your tykes can wear for Halloween, Comicon, Movie Night, or just because!

Nano Roboto Costume

We really like the homemade nature of this costume! It looks like something a Toddler put together with the help of an older sibling, parent, or grandparent. Just don’t go out in the rain with it on…

Witch Hat For Toddlers

Top off your Toddlers’ Halloween look with this adorable hat. It’s perfect for a full witch ensemble, or even as an accessory over a casual but festive outfit. Either way, it’s super cute!

SIMBLREEN ’21

Sometimes it’s best to keep things simple, and you can’t go wrong with a classic ghost costume. There are 5 swatches to choose from with options for Children and Toddlers, too!
