Quick Summary
The best baby Halloween costume is comfortable, easy to put on and take off and fits your child properly, according to What to Expect community parent testers. And of course, it has to be cute!
What’s the only thing cuter in this world than your baby? Dressing them up in the most adorable baby Halloween costume, of course! Taking part in this Halloween tradition is so much fun: You can coordinate with your little one or get everyone involved with family Halloween costumes (we also have maternity costume ideas for anyone who's expecting, too!). Or, if you're simply dressing up your baby to snap a quick photo for the ‘gram, that’s okay too! They’re only this little once, after all.
Although Halloween is almost here, there are still so many adorable last-minute baby Halloween costumes to choose from that will arrive in time. You're bound to find the cutest baby costume idea, with options ranging from adorable to silly to (a little) scary. Choose a character from your favorite storybook or kids’ shows, opt for a classic Halloween monster, or go straight up cute and dress your tot as their favorite animal. No matter what direction you go in, we're sure that you'll find a winner ahead, with newborn Halloween costumes, costumes for older babies and toddler costumes, too.
How we chose the best baby Halloween costumes
The best baby Halloween costumes are comfortable, easy to change and fit properly. Still, there are other important factors that we considered when choosing the best baby Halloween costumes, including:
- Comfort: You’ll want soft fabrics like cotton or fleece that won’t scratch or irritate baby’s soft skin. Avoid options with tulle or lace around the face or hands, which can be irritating. Do your best to pick a costume that matches the temperature, too. A head-to-toe furry costume isn’t ideal for a sunny day, nor will a thin onesie work on a chilly evening. When in doubt, layer.
- Design: If your baby will be wearing the costume for an hour or longer, save yourself a headache and look for one that allows easy access for diaper changes. Many have snaps along the inseam or leggings that are easy to take on and off.
- Safety: Costumes should be the right size for your baby. They also shouldn’t have small parts or accessories that could break off and cause a potential choking hazard. And you should avoid anything with pieces that cover their nose or mouth for the same reason. According to American Academy of Pediatrics (AAP) recommendations, costumes should also clearly say “flame resistant” on the label.
You should also keep the following tips in mind when looking for infant Halloween costumes:
- Follow your baby’s lead. If your tot won’t wear a hat for longer than 60 seconds, save yourself a headache and pick a costume that doesn’t depend on a hat or hood to look complete.
- Consider cost. Given how quickly babies grow, this is likely a costume that your little one will wear for just this year’s festivities. Unless you plan on saving a costume for the next baby in the family, don’t feel like you have to spend a ton on a great look.
- Keep a spare on hand. Considering how common blowouts are among babies, the AAP recommends having a backup costume in case your little one has a leaky diaper or spits up while out on the town.
