30 Baby Halloween Costumes, From Animals To Avocados

There’s something for every family here.

Originally Published: 

Whether they’re only a few weeks old or a few months old, you probably want your baby’s first Halloween to be as memorable as possible. They might not be able to truly appreciate trick-or-treating, eat any Halloween candy, or go to a party without falling asleep in their stroller a few minutes in, but that doesn’t mean they have to be left out of all the festivities. The best way to make your little one’s first Halloween special is to get them an adorable baby Halloween costume that will help to create the perfect photos (whether they’re napping or awake).

And when it comes to baby Halloween costumes, there are so many sweet options. You could dress them up as their favorite food — an avocado, perhaps — or you could opt for a cute animal, like a cat or a little lamb. You could always go for a classic favorite like a pumpkin, or you could try something a little bit different — think Beetlejuice or a spooky werewolf. We’ve rounded up all of these options and more so that you can find the best costume for your baby, whether they are still a tiny little newborn, an infant just starting to focus their eyes, or a baby sitting up and chewing on everything they can reach. Check them out below… and good luck on picking just one. They’re very hard to resist.

A beloved Sesame Street character

This Cookie Monster costume is almost too cute to handle. If your little one loves watching Sesame Street, then dressing them up as one of the beloved characters on the show is a great idea. Of course, Cookie Monster is a beloved and iconic character. This fuzzy blue suit will keep them nice and cozy if the weather on Halloween is chilly, too.


A cuddly ghost

Finding the perfect Halloween costume for a newborn is not easy. Babies who are under three months (or, really, under six months) spend a lot of time sleeping, being held, or strapped into a stroller or car seat. Enter this Baby Ghost Bunting. It fits just like a comfy sleeper and it even comes with a little hat to keep them warm. They can wear it before and after Halloween, too.


An avocado

If your baby loves avocado, then this is a perfect choice for a baby Halloween costume. The avocado costume set comes with everything you need for under $25: A plush body suit shaped like an avocado, a white shirt to go underneath, and striped leggings that complete the whole look. You don’t have to add anything else… except maybe a cup of mashed avocado to keep them busy (and keep things authentic).


A peacock

This over the top peacock costume is truly amazing. The colorful feathered tail, the hood with the beak, the warm and cozy slippers… this is just so cute and different. This one probably isn’t ideal for newborns who are just going to be laying in a stroller (the large feathers in the back could get in their way and just be annoying for them, which is the last thing you want), but it’s better for slightly older babies who can sit up and maybe crawl around a bit. I love how cute and silly this idea is.


A superhero

When your baby is really little, it can be hard to get them in a costume that involves a lot of padding or plush, or something with added accessories. If you want to keep things as simple as possible, a bodysuit is the way to go. This Superman one will make your baby look like Superman — abs included — and it even has a little cape with it as well. It’s comfortable and ideal for areas where the weather might be warmer on Halloween (although you can also add leggings if it’s chilly), and it will look just as cute in a stroller as it will out.


A dog

Few things are cuter than this ultra fluffy dog costume. It’s a one-piece, so it’s really easy to get on and off, and it’s made of a super soft material that will keep baby warm and cozy all day long, especially with the hood up. This is even sweeter if you have a dog — it’s a missed opportunity if you don’t put your baby in this tiny costume, then seat them next to your dog to take photos. It’s perfect for the baby who is already best friends with their dog. Basically, I’m completely obsessed.


A dragon

Forget the fluffy animals and delicious food options for a minute and opt for something more in the realm of fantasy and sci-fi. This miniature dragon costume is so much fun and a little bit more unique. It’s a one-piece jumpsuit that comes with wings and booties shaped like dragon’s claws, and it’s completely adorable. A big bonus is that there are inseam snaps for easy diaper changes, and the wings can snap on and off, so when you need to lay them down in a stroller you can make them a lot more comfortable. This convenient, cozy and adorable choice is a fun one.


A deer

If you want to dress your baby in an animal costume but don’t want to put them in a one-piece fluffy jumpsuit, there are still options. This deer costume is one of them. The dress is cute and easy to get on and off, and then you can customize it as you want to. You can easily add white or brown tights and a pair of booties, and if it’s too chilly, you can also add a long-sleeved white bodysuit underneath. The costume also comes with a headband that they’ll *probably* keep on and is too sweet for words. And the price? At just under $16, it’s hard to beat.


A giraffe

This comfortable giraffe one-piece costume is an easy one for keeping baby cozy. Instead of being an actual Halloween costume, it’s a giraffe-printed pajama set with a hood that features ears. This makes it ultra-cozy and comfy for baby and you don’t have to worry about them being cold. It’s also versatile, since it can be worn for more than just the holiday.


A Disney character

Instead of the usual Disney princess costume, opt for something a little more unexpected. This fairy godmother costume is inspired by Cinderella’s fairy godmother and is so cute and different. Made for babies as young as 0-6 months, this costume is pretty low-maintenance and also nice and cozy thanks to the hooded cape. It features a skeet tutu skirt and the huge bow in the front is adorable.


A ladybug

As far as insect costumes go, ladybug ones are easily the cutest. This ladybug costume features a red and black dress with a tutu skirt, detachable wings, and a headband that looks like their antenna. It’s really sweet and comes in at an awesome price point for something you’re probably only going to use once — under $20. You can also easily add black tights and maybe even a black long-sleeved shirt underneath to keep your baby warm if you need to.


Charlie Brown

This Charlie Brown costume definitely has to be one of the cutest baby Halloween costumes, and it’s really perfect for babies who barely have any hair on their heads just yet. It comes with a yellow and black onesie and a pair of little brown booties, so it’s very simple. You can add black or brown leggings to complete the outfit, and maybe even a black or brown long-sleeved top underneath. This one feels less like a costume and more like a normal outfit, so it’s great for babies who are get uncomfortable and don’t like a lot of added accessories.


A lamb

There’s something about this little lamb costume that I personally absolutely adore. It’s just so sweet and cute, and it’s perfect for a tiny newborn baby. It’s soft and fuzzy and plush without being too heavy or overwhelming, and it’s easy to get on and off baby whenever needed. The lamb face on the hood is so cute. You have the option to either have your little one either just wear this, or pair it with white or cream colored leggings and a long sleeved shirt. They’ll look so cute snuggled up in this in the stroller.


A bat

Want to do a costume that is really cute but also feels spooky and just right for the Halloween season? Then this bat costume is perfect. The costume itself is actually a black onesie, essentially, so you really don’t need to add anything else to it. The wings are underneath the arms, which is perfect for a wiggly little baby: There’s nothing you need to attach and it’s always comfortable to hold them or lay them down. And the hood with bat ears on it is ideal for keeping your babe warm and in character.


A scarecrow

Another costume idea that is perfect for the Halloween season and gives off all of the fall vibes is this tiny scarecrow costume (and it’s not spooky or creepy at all). This sweet baby Halloween costume comes with everything needed to complete the look: The dress, the pants, the collar that looks like straw hay, and the hat, which has straw “hair” coming out of the sides.


A butterfly

This baby butterfly costume is so adorable and it would look great on babies who aren’t mobile or babies who are crawling around or walking. The pullover style top has a comfy oversized fit and can be worn over tights or leggings, making it really easy to pair with just about anything. The hood is a cute feature with the ears and also keeps them warm, and the wings are small enough to not be obnoxious.


A Flintstones character

This Pebbles costume is definitely not the cheapest option out there (it costs over $100, so it’s not in everyone’s budget), but if you want to spend the money, it’s very adorable and authentic. It comes with a one-shoulder dress with a black tutu underneath and the cutest little bone and bow for their hair. You can get this in 6 months or 9 months.


A bunny

As cute as some of these baby costume options are, some are just a little too elaborate for a really tiny newborn — we’re talking 0-3 months old. If you want to dress up a newborn for Halloween, you want them to be in something comfortable. That’s this rabbit onesie. It has a zipper down the front for easy changes, it’s super warm and cozy, and it’s just extremely cute to look at. Your baby will easily be able to nap and lounge in this one. And while it looks appropriate for Halloween, it can also be worn at any time.


A baby shark

Speaking of costumes that are super easy for very small babies to wear, even when they’re laying down, there’s this shark costume. The comfy one-piece doesn’t feature legs, just a shark-like tail, making it easy for them to get comfortable when they’re laying in their stroller all day while trick or treating. It’s cute with or without the hood up, and we love that the “fins” go over the hands to keep them from scratching themselves and to act as mittens.


A pumpkin

This classic baby pumpkin costume comes with a bubble romper shaped like a pumpkin and a matching hat that looks like the top of the pumpkin, as well as orange booties. It’s simple and low-cost, and you can easily customize it as you want: Add green and white striped leggings or a pair of black leggings and a black long sleeved shirt. Yes, a bunch of other babies might also be dressed as pumpkins, but embrace it by seating them all together and taking a photo of their tiny pumpkin patch.


A werewolf

Another spookier option that is also just really adorable is a werewolf. It’s perfect for Halloween and it’s very simple: It’s just the dress and the hairy headpiece. This is a costume for a werewolf, but it could also double as the wolf in the Little Red Riding Hood story, making this a perfect choice for a matching siblings costume. Have their sibling dress as Little Red Riding Hood, and Baby can be the Big Bad Wolf.


A dinosaur

This pink-and-purple dinosaur costume is so adorable, comfortable, and warm. It’s a jumpsuit, so it’s really easy to put on. The hood features a dinosaur head that little ones will get a real kick out of, and the oversized hands will keep their hands nice and warm. The feet are also padded on the bottom so that early walkers won’t slip and fall.


A mouse

This mouse baby Halloween costume is so simple, great for newborns, and nice and cozy. It’s also very adorable because, while mice might be annoying pests sometimes, they can also be very cute, especially when your baby is dressed as one. The soft handmade jumpsuit is very simple: Just white with long sleeves and some buttons. It also comes with the little hat to keep your babe warm.



It’s safe to say your baby’s favorite movie probably is not Beetlejuice, but that’s OK: You only have a limited number of years where you get to pick costumes for your little ones based on what you like, too. And this spooky Beetlejuice costume is truly perfect. It comes with a black-and-white striped jumpsuit that is just iconic to the character, and that’s all you really need. Feel free to add some makeup if you want, but you don’t have to. And I love this as a family costume if everyone else wants to dress up as other characters in the movie.


An astronaut

It’s time to show your little ones that absolutely anything is possible: Even being a baby astronaut. In all seriousness, this Aeromax Jr. astronaut costume is adorable, even more so because it is so realistic looking. If you want a costume that isn’t all fluff and adorable ears, then this astronaut costume is a great choice. It’s comfortable, easy to put on, and doesn’t really need any extras.


A very famous marshmallow

This Stay Puft marshmallow costume is the best and most clever way to dress your little one up as the cutest ghost on Halloween night. Featuring the hat, costume, and leggings with attached boot covers, this comes with everything you need to make this costume a huge success.


A llama

There are tons of animal costumes out there for babies, and you’ve likely seen or done the cliches: Cats, dogs, bears, etc. Those are all adorable and there’s nothing wrong with them, obviously. But this Lil’ Llama costume? It just hits differently. With the cute hood and ears and the colorful detachable trim, this feels fun, playful, and a little unique, all things you want in a great Halloween costume.


A sloth

Speaking of cute animal baby Halloween costumes, don’t sleep on this cut sloth costume. It’s another option that is a little more unique, and it really embodies a baby perfectly. Sloths love to sleep and cuddle, and they really only wake up to eat and move about very slowly. That basically describes a newborn baby. This comfy and cuddly one suit costume is bound to keep them warm and happy.


A skeleton

This simple, classic skeleton costume looks and feels more like pajamas or an everyday outfit and it comes in at under $20, which is great. It also comes with an orange hat. It might not be elaborate, but it is perfect for Halloween.


A rooster

A rooster? Yes, a rooster. This Dress Up America rooster costume is much more adorable than you’d think it would be. It’s basically like a sleeveless jumpsuit, and you can keep it like that if it will be warm, or you can have them wear it over a long-sleeve onesie and a little pair of pants or tights. This is easy to put on and take off and it will definitely steal the show.

Whether you go for the cute and fuzzy animals or the fun and unique options, you can’t go wrong. A Halloween costume on a baby is always going to be memorable!
