Best Baby Halloween Costumes for 1-4 Months

For the youngest babies, one-piece costumes and onesies are the best choice. Tiny babies sleep, wiggle, and spit up, so skip hats that slip, scratchy fabric, and anything with small pieces. Soft, stretchy, snap-friendly outfits make diaper changes easy and keep your baby comfortable.

  • Ladybug: A red onesie with black dots and a little pair of antennae is a classic baby Halloween costume. It’s simple and sweet, and you can even DIY it with felt circles.
  • Skeleton: A black onesie with white bones is spooky-cute and works for any baby. Many are glow-in-the-dark, which makes for fun evening photos.
  • Pumpkin: An orange onesie with a stem beanie is the ultimate first Halloween look. Bonus: it pairs perfectly with a real pumpkin patch photo.
  • Bat: Soft wings and a onesie make this one irresistible. Check out this adorable bat costume for inspiration.
  • Spider: Add extra stuffed legs to a black onesie for a friendly little spider. This little spider costume is a great example.

Cute Family Costumes With Baby

Coordinating costumes make the memories even sweeter. Here are some ideas to get you started.

Two Parents + Baby

  • Three Bears: Dress up as Mama Bear, Papa Bear, and Baby Bear. Brown or tan sweatshirts with ear headbands are comfy and easy.
  • Milk and Cookies: Have your tallest family member dress as a carton of milk. Everyone else can wear brown with black polka dots – an easy chocolate chip cookie costume. You can do a simplified version of this family costume.
  • Farmers and Flower: Wear overalls and flannel. Put baby in a green onesie and a bonnet with flower petals. If you want to go the extra mile, you can decorate your baby carrier as a pot. Get inspired with this example.
  • Astronauts and Alien: You can wear space suits, while baby wears a green onesie with antennae.

Two Parents + Toddler + Baby

  • Wizard of Oz: Dress as Dorothy, the Scarecrow, and the Tin Man, with baby as Toto in a tiny puppy hood.
  • The Incredibles: Get red suits and masks for everyone, with baby as Jack-Jack.
  • Fishing Family: This playful group costume casts parents as fishermen, toddler as a fisher-kid, and baby as the catch of the day.
  • Peter Pan: To capture this classic story, parents dress as Wendy and Peter with toddler and baby as Tinker Bell and the crocodile.

Get in the Photos, Too

When you’re busy dressing up your little pumpkin, it’s easy to forget that you are an important part of this moment. Get in the photos, too.

Years from now, your child will love seeing who was holding them on their first Halloween. Prop your phone on a shelf and use a timer, or ask a friend to snap a few shots of the whole family. You don’t need to be in costume. Being in the picture is what counts.
