Baby Halloween Costume Ideas 2019 – Best Costumes For Babies

10 Cute Baby Halloween Costumes

October 8, 2019 Updated February 22, 2020


Baby Halloween costumes are so freaking adorable, it’s almost frightening how many swoon-worthy options there are these days. Let’s face it: Baby’s first October 31st is less about Baby, and more about Mommy finding and securing the most aw-dorable costume on the shelf (or the web). And it’s not just about a cute photo op, either — a picture of Baby in their Halloween costume could be holiday card potential, work as a birth announcement, or, better yet, Insta click-bait.

But here’s the predicament when it comes to choosing the best Halloween costume for your baby: Your bundle of joy is so itty-bitty, they can’t relay their interests for no reason other than the fact that they have none. Your kiddo could care less who they’re dressing up as, or what jar of food gets dropped into their jack-o-lantern bucket. As long as a warm bottle is in their near future, they’re content. 

So what’s a mama to do? How’s a mama to choose? To help narrow down your options, we’ve rounded up some of the cutest baby Halloween costumes available online right now. 

Amscan The Incredibles Baby Jack-Jack Halloween Costume



Amscan’s The Incredibles Baby Jack-Jack Halloween costume is super cute. The one-piece jumpsuit is also super comfy and is an exact replica of the superheroes uniform in the animated film. Complete with black eye mask and Incredibles logo, your baby will have everything they need to fight crime with cuteness.

Princess Paradise Baby Girls’ Premium Laura The Lamb



Is there anything sweeter than Princess Paradise’s Premium Laura the Lamb Halloween costume for babies? Your little bundle of joy will look angelic in this four-piece outfit complete with bubble body, hood, and chenille feet covers. Just be aware of the weather report on October 31, because this bodysuit definitely isn’t made for cool conditions. Add a long-sleeved shirt and tights for good measure if the foreseeable forecast is chilly.

Rubie’s Elvis Presley Onesie Baby Costume



Austin Butler might have just snagged the role of Elvis in the anticipated 2021 biopic, but on October 31, 2019, it’ll be your baby who portrays the king. Clad in the classic white suite with popped collar, you’ll be saying “thank you, thank you very much” on repeat with all the compliments you’ll receive over this hilarious baby Halloween costume. Pro tip from the reviewers: Size up. 

Cuddle Club Funzies Fleece Baby Bunting Onesie Dino Jacket



As far as we’re concerned, Cuddle Club’s Dino Onesie is the best onesie because it’s unisex, comes in four different colors (green, grey/black, purple/green, and pink/grey), and can easily blend into the pajama drawer after Oct. 31. Plus, because this baby Halloween costume is made with durable fleece, it’ll likely be warm enough to wear as-is while trick-or-treating (but of course pack a jacket just in case).

Pottery Barn Kids Baby Piglet Costume



Think your baby’s adorable now? Add a pig snout and curly tail on for size! Pottery Barn Kids has farm animal costumes for babies in the bag, and this piglet costume is one of our favorites. Not only is this Halloween costume super baby-friendly, with metal snaps at the jumper’s diaper area for quick and convenient changes, but the material is also hypoallergenic and color-treated with environmentally safe dyes.

InCharacter Lil’ Lion Infant Costume



Any Wizard of Oz fans out there? InCharacter’s Lil’ Lion, tail bow and all, reminds us of Dorothy’s furry friend, only this king of the jungle is anything but cowardly; it’s cuddly, sweet, and full of giggles. The costume itself isn’t exactly heavy, but it’s made from polyester, and with a lot of different pieces involved, can get very warm, very fast.

Carter’s Little Avocado Halloween Costume



Avocados are in high demand because they’re delish and taste better than butter on toast. Evidently, avocados are also adorable as Halloween costumes, so if your baby is going to pose as a fruit this year, you might as well make it this little green guy from Carter’s. Complete with avocado jumpsuit, white long-sleeved shirt, and green striped socks, it’s all you avo wanted for your baby’s Halloween costume. 

Party City Baby Lil Hogs Wizard Costume



It’s pretty bizarre to think that the first generation of Potterheads are at the age of procreation, but we digress. Your child might be too young to understand that magic that is the wizarding world of Harry Potter, but at least the Instagram photos will be enchanting. Though Party City’s Lil Hogs Wizard Halloween Costume for babies is kind of Hogwarts-meets-hipster-cafe, we can dig it. Converse not included, but strongly advised.

Hyde and EEK! Boutique Baby Plush Pumpkin Halloween Costume Vest



If you don’t dress your baby up as a pumpkin for their first Halloween, we’re going to judge you (just kidding — sort of). Forget Reeses Pieces and Hershey Bars, the only eye candy we see is this super sweet Hyde and EEK! Boutique’s Plush Pumpkin Halloween Costume Vest. The ensemble consists of an orange plush vest, matching hat, and green and white striped shirt and leggings for a pop of color. It’s coordinated and cute, just like the obligatory first-Halloween photo you’ll upload on your Insta feed.

Leg Avenue Where the Wild Things Are Baby Max Costume



There’s a wild thing in every growing babe; some just hide it better than others. (Until sugar’s involved; then all bets are off.) Unleash your little one’s inner beast on Halloween night with this majestic costume straight out of Maurice Sendak’s imagination. There’s really nothing monstrous about Leg Avenue’s cozy onesie. In fact, it’s multi-faceted. It can pass for a birthday suit or winter pajamas.
