Our soft, affordable baby costumes come in a range of styles and themes to delight everyone! Our baby boy and baby girl Halloween costumes are made with comfort in mind so your little one can enjoy the holiday even more. 

Halloween Costumes for Newborns from 0-3 Months

It's your baby's first Halloween costume, and of course they'll be the cutest. Dress your soft, sweet bundle of joy as a snuggly bear or lamb, a cute pumpkin or an adorable kitten or puppy. Your infant will look charming in a baby Mickey or Minnie costume or as Winnie the Pooh from the Hundred Acre Wood. A newborn's only job this Halloween is to look their adorable best for their album photos, and you'll find everything you need to get them the right costume sized for 0-3 months.

Smiling & Laughing with Funny Costumes for Babies from 3-6 Months

At this stage of a baby's life, they're discovering their smile and their giggle, and you might even get some two-toothed grins from behind their Halloween costumes. Baby can now hold up their head and sit up. Roly-poly, chubbier-cheeked cherubs from 3-6 months look adorable as hatchlings or baby animals, and our infant costume selection has all your barnyard favorites. You can also go for funny baby Halloween costumes by dressing your wee one as a wise baby Yoda, the Stay Puft Marshmallow Man from Ghostbusters, or as a skunk if they're a lil' stinker!

Cute Baby Costumes for 12-Month-Olds and 18-Month-Olds

Your older baby is now on the move, crawling, walking or running! Halloween costumes for 12-18 month olds are designed with this curious and constant energy in mind. This is a great age for our Disney baby costumes. Your older infant or toddler will love dressing up and moving around as one of their favorite characters such as Woody, Jessie, Buzz or Rex. With dozens of choices of cute, funny and comfortable Halloween costumes, your toddling infant will look and feel their best.
