40 Best Halloween Costumes for Babies in 2026: Adorable & Cozy Picks!
The best Halloween costumes for babies in 2026 are soft, one-piece outfits that are easy to get on and off, like a plush pumpkin, a fuzzy bee, or a tiny Disney sidekick. We rounded up 40 of our favorites on Amazon, from newborn to 24 months, so you can order early and skip the costume-aisle scramble.
Your baby won't remember their first (or second) Halloween, but you will, and so will your camera roll. The trick is finding something cute enough for photos and comfy enough for a stroller nap, a car ride, and a few hours of being passed from grandparent to grandparent. Below, every pick is sorted by style, with sizes, why we love it, and a quick parent tip.

Safety: Look for "flame resistant" on the label, skip small parts that could come loose, and choose a hat or hood over a mask.
When to buy: Order by mid-October so there's time to exchange sizes before Halloween on Saturday, Oct. 31, 2026.
How to Choose the Best Halloween Costume for Your Baby
Babies have three jobs on Halloween: look adorable, nap anywhere, and survive at least one surprise diaper change. A great baby costume makes all three easy.
Pick Comfort Over Accessories
Look for one-piece rompers, buntings, and hooded jumpsuits in soft fleece or plush. Skip stiff headpieces that scratch or slide, and pack a regular hat in case the costume hat gets tossed in the first five minutes.
Size Up (Especially if It's Cold Out)
Babies grow fast between ordering day and Halloween night. If your baby is near the top of a size range, go up a size so a onesie or footed pajamas can fit underneath. We list the sizes Amazon showed for each costume at the time of writing, but always check the size chart on the listing before you buy.
Check the Safety Basics
The American Academy of Pediatrics recommends looking for "flame resistant" on costume labels and choosing decorative hats over masks so nothing blocks your child's view. The U.S. Consumer Product Safety Commission adds that costumes should be short enough to prevent tripping and bright or trimmed with reflective tape so drivers can see them after dark.
For babies, also watch for small buttons, pom-poms, or glued-on pieces that could come loose, since little ones put everything in their mouths. Take off any hood or headpiece before naps.
Plan for the Car Seat and Stroller
Puffy costumes and car seats don't mix, because bulky layers can keep the harness straps from fitting snugly. Buckle your baby in wearing regular clothes and change into the costume when you arrive, or choose a thin, snug romper. A carrier cover is another easy option if you're babywearing.
Dress for LA's Halloween Weather
Halloween in Los Angeles can feel like summer in the afternoon and like sweater weather after dark, especially near the coast. A sleeveless or lightweight romper works for daytime parties, while a fleece jumpsuit is better for evening trick-or-treating. Check the forecast that week and bring a layer you can add or peel off.

Baby Halloween Costume FAQs
What is the best Halloween costume for a newborn?
For newborns, soft romper-and-hat sets and plush buntings work best because they're easy to put on and comfortable for long naps. Look for sizes that start at 0 to 3 months, like a pumpkin romper, skeleton jumpsuit, or ghost hoodie romper, and skip costumes with small pieces that could come loose.
What size Halloween costume should I buy for my baby?
Buy the size your baby will fit on Halloween, not the size they wear today. If your baby is near the top of a size range, go up a size so a onesie or footed pajamas fit underneath. Always check the brand's size chart on the listing before you order.
Are baby Halloween costumes safe in car seats?
Bulky or puffy costumes can keep car seat harness straps from fitting snugly. It's safest to buckle your baby in wearing regular clothes and put the costume on when you arrive. Thin, snug rompers or a carrier cover are easier options for babies who will be riding in the car.
When should I buy my baby's Halloween costume?
Order by mid-October. That leaves time for shipping, a try-on, and an exchange if the size is off before Halloween on Saturday, Oct. 31, 2026. Popular character costumes in infant sizes can be harder to find closer to the holiday, so earlier is better.
Where can I take my baby trick-or-treating in Los Angeles?
Daytime events are ideal for babies because they end before bedtime. Many LA malls, farms, libraries, and theme parks host gentle Halloween activities in October. See our guide to toddler Halloween events in LA for current dates and ideas.
