Planning your baby’s first (or fifth!) Halloween costume? You’ve come to the right place. Whether you’re team DIY or team “just add to cart,” picking a baby Halloween costume should be fun, not stressful.

Halloween costumes for babies sell out fast, especially the cute ones, so the earlier you start browsing, the better your odds of snagging your favorite. To make things easier, I’ve rounded up over 30 of the best baby Halloween costume ideas for 2026, from classic critters to food-inspired fits to easy homemade options. Keep scrolling to find the perfect costume for your little pumpkin!

1. Sunflower

A sunflower costume is bright, cheerful, and surprisingly simple to put together. Pair a yellow petal collar or headband with green leggings or a green onesie, and you’ve got yourself an adorable garden-fresh look. This one photographs beautifully outdoors if you’re planning a fall photo session.

2. Ice Cream Sundae

Sweeten up Halloween night with an ice cream sundae costume. A soft, rounded cream-colored bodysuit topped with a felt cherry headband and pom-pom “sprinkles” makes for one seriously scoop-able outfit. Bonus points if you match with an older sibling dressed as a banana split.

3. Winnie the Pooh

This storybook bear never goes out of style. A honey-colored sweater, a red top, and a soft bear-eared hat will have your little one looking just as sweet as a pot of hunny. It’s an easy costume to build from pieces you may already have in the closet.

4. Baby Lion

Let your little one rule the jungle in a fuzzy lion costume. A tan or caramel onesie paired with a homemade felt mane (hot glue and a plain beanie will do the trick) creates a costume that’s both cozy and cute for cooler October nights.

5. Friendly Spider

An all-black outfit is the base for this eight-legged look. Stuff a couple of long black socks, sew them onto the back of a sweater, and add oversized googly eyes to a beanie for a spider costume that’s silly rather than spooky.

6. Bunny Rabbit

A bunny costume is a Halloween classic for good reason. Floppy felt ears on a headband, a fluffy white tail pinned to the back of a onesie, and pink accents around the nose and cheeks make for one hoppy little outfit.

7. Bat

Keep the all-black theme going with a bat costume. Add a pair of soft fabric wings to any dark outfit, and you’ve got a costume that’s easy to move (and nap) in. Sparkly leggings or a tutu are a fun twist for baby girls.

8. Ghostbuster

For movie-loving families, a mini Ghostbuster costume is an instant crowd-pleaser. A jumpsuit, name patch, and a foam proton pack (or a simplified version for younger babies) will have grown-ups asking for photos all night.

9. Astronaut

Send your baby out of this world with an astronaut costume. Puffy white suits with mission patches are widely available and comfortable enough for babies who don’t love bulky costumes, since most are made from soft, stretchy fabric.

10. Jack-O’-Lantern

You can’t go wrong with a classic pumpkin costume on Halloween. An orange bodysuit, black felt facial features, and a green beanie “stem” are all you need. This one’s easy to DIY in an afternoon.

11. Raggedy Ann

This vintage doll costume is full of personality. Look for a red yarn wig, striped stockings, and a pinafore dress to complete the look, or build it piece by piece for a totally custom take.

12. Lemon

Citrus costumes are having a moment, and a lemon costume is a fresh, zesty pick. A yellow onesie or lemon-print set paired with a green leaf headband keeps this one simple and sunny.

13. Baby Elephant

An elephant costume, gray and gentle, is perfect for babies who’ll be swaddled or worn in a carrier most of the night. Floppy fabric ears and a curled trunk hood make this costume as sweet as it is cozy.

14. Strawberry

A red onesie, green felt leaves, and a scattering of black “seeds” turn any baby into the berry cutest trick-or-treater on the block. This is one of the easiest fruit costumes to DIY from scratch.

15. Little Monster

Channel a favorite monster movie with a colorful, googly-eyed onesie costume. These are typically soft, plush, and machine washable, which makes them a practical pick for younger babies who are still spitting up or teething.

16. Chicken

A feathery chicken costume is silly, cute, and surprisingly easy to find pre-made. For a DIY version, glue soft craft feathers to a white onesie and top it off with a red felt comb headpiece.

17. Unicorn

Magical and glittery, a unicorn costume is a go-to for a reason. Pastel stockings, a flowy dress or onesie, and a horn-and-ears headband come together for a costume that’s pure whimsy.

18. Ghost

A ghost costume is about as classic as Halloween gets. A white sleep sack with felt eyes works beautifully for newborns, while older babies can wear a white onesie, dress, or set with simple black facial details.

19. Baby Witch

A witch costume can be as playful or as polished as you like. A black dress, striped tights, and a mini witch hat make for an outfit that’s more “cute” than “creepy,” perfect for a baby’s first Halloween.

20. Garden Fairy

Wings, a floral crown, and a soft tulle dress make this fairy costume feel enchanted without being fussy. It’s a lovely pick if you’re planning outdoor fall photos alongside trick-or-treating.

21. Baby Shark

Whether it’s the song or just a love of the ocean, a shark costume is always a hit with the toddler crowd. Look for a soft, hooded onesie style in classic gray or a fun pastel shade.

22. Pizza Slice

A felt pizza costume is endlessly customizable. Start with a yellow (cheese) onesie base and glue on felt pepperoni, mushrooms, or peppers for a topping combo as unique as your family’s go-to order.

23. Cabbage Patch Kid

This nostalgic costume is a sentimental favorite for parents who grew up loving these dolls. Yarn pigtails, rosy cheeks, and a gingham dress or overalls bring the vintage charm to life.

24. Cartoon Best Friend

Recreate a beloved cartoon character with a simple sweater, collared shirt, and round glasses combo. This is a great option if you want a recognizable costume without spending a lot on a licensed set.

25. Potted Plant

One of the most creative DIY costumes on this list, a potted plant costume uses a hollowed-out planter as the base, with painted pom-poms or felt leaves strung together to look like trailing greenery.

26. Taco

Fold a soft tan or beige blanket or bodysuit into a taco “shell” shape and stuff with felt lettuce, tomato, and cheese pieces for a costume that’s every bit as fun as it looks in photos.

27. Baby Dinosaur

A plush, spiky dino costume is a favorite for a reason: it’s warm, comfortable, and endlessly cute. Look for a soft hooded onesie style in green or a fun non-traditional color like lavender or teal.

28. Cowboy or Cowgirl

Denim overalls, a plaid shirt, a bandana, and a mini felt cowboy hat make for an easy, western-inspired costume that works just as well for a fall photo shoot as it does for trick-or-treating.

29. Baby Owl

A brown or gray feathered onesie with a pair of soft ear tufts creates a woodland-ready owl costume. This one’s a great pick for a nighttime stroller stroll since it keeps baby warm.

30. Mermaid

A shimmery tail-inspired skirt or bodysuit paired with a seashell-accented top (or a simple onesie for younger babies) makes for a costume that’s whimsical without being difficult to wear.

31. Superhero

Capes are a costume shortcut every tired parent can appreciate. Pair a simple onesie in your baby’s favorite color with a felt cape and matching mask for an easy, comfortable superhero look.

32. Farm Animal Trio

If you’re dressing multiple little ones, coordinating farm animal costumes (think cow, pig, and sheep) make for an adorable group photo and are usually easy to find as matching sets.

Frequently Asked Questions

What age can babies start wearing Halloween costumes?

Babies can wear Halloween costumes from newborn age onward, but comfort and safety should come first. Newborns tend to do best in soft, loose costumes worn briefly for photos. Once your baby can hold their head up on their own, usually around 3 to 4 months, you’ll have more costume options to choose from. Always avoid small detachable pieces, tight elastic, or heavy headpieces.

Should I buy a baby Halloween costume or make one myself?

Both options work well depending on your time and budget. Buying online is convenient and saves time, but costumes can sell out, so order at least 4 to 6 weeks before Halloween. DIYing is budget-friendly and lets you personalize the look, and many simple costumes, like a strawberry or ghost, require minimal sewing skills and materials you likely already have at home.

How do I keep my baby safe and comfortable in a Halloween costume?

Stick to soft, breathable fabrics and steer clear of small pieces that could pose a choking hazard. Make sure the costume isn’t too tight or too warm, since babies can’t regulate their body temperature as well as older kids. Dress them in layers underneath for chilly nights, and skip masks or headpieces that could block breathing or vision.

What baby Halloween costumes are trending for 2026?

Classic and food-themed costumes remain popular year after year, think pumpkins, animals, flowers, and sweet treats. For 2026, cozy plush animal costumes and nostalgic character looks are especially popular. At the end of the day, the best costume is the one your baby will actually tolerate wearing, so prioritize comfort over complexity.
