Halloween Costume Ideas for Baby

I love Halloween and I have to say it is so much more fun with little ones around!  The only way a baby could possibly be any cuter than he/she already is would be dressed up in an adorable Halloween costume.  They are all so cute it is hard to pick just one!  I have to admit that I have bought multiple costumes for the same year when I know we have a number of different places or events they can wear them.

In my experience when buying costumes I do find that they tend to run large.  I like to read reviews or look into the sizing information carefully before buying, especially for baby! Take a look at these great costume ideas for your baby this Halloween!

Baby Butterfly Costume

This butterfly costume is just so adorable for a sweet baby girl!  These soft sack like costumes are perfect for the youngest babies on Halloween since it keeps baby warm and cozy and you don’t have to struggle to fit legs in.

Colorful Caterpillar Baby Costume

If you have twins why not add a caterpillar to your butterfly!  This costume reminds me of the Very Hungry Caterpillar which my toddler absolutely loves.  Another great option for a little baby with the sleep sack like design.

Maybe someone with triplets wants to add a flower to the caterpillar and butterfly! LOL! But seriously, this flower costume could not be any cuter.  I can just imagine the adorable photos with this.  You could even do a garden theme for the whole family!

Have a handsome little baby boy?  Why not dress him in a suit? A penguin suit that is!  I love the added little red bow-tie too.  This would be great to do a full family of penguins for the group Halloween costume as well!

Super cute little baby bat costume with the bright Halloween colors!  Just love the little wings on the back and looks cozy and warm for baby.

This octopus costume looks like so much fun!  This would be perfect for an under the sea family costume idea too!

Another great under the sea costume!  Get the Mommy Shark and Daddy Shark T-shirts and you have a whole family Halloween costume!  And if you don’t know the family shark song these are based on, look it up!  Your kiddo will love you for it.

How could you resist this sweet cute puppy dog!  All kids love puppies so I’m sure they will love being one for Halloween! Looks so soft and cozy for baby.

What little girl does not love ponies?  And what mom doesn’t want to dress her sweet baby girl up in the adorable pony costume?  So adorable!

Monsters University Baby Sulley Costume 12-18 M - image 1 of 1
Monsters University Baby Sully Costume

I have loved Monsters Inc. since it first came out and Sully was a favorite.  This costume will be perfect for your little monster!

Panda Halloween Costume Infant 3-9 months - image 1 of 1
Huggable Baby Panda Costume

This is a genius baby costume!  It has extra long arms and legs to wrap around the parent carrying baby!  I have never seen these types of costumes before so I may have to try this one myself as I will have a 5 month old this Halloween!

Fearless Lil Lion Baby Costume 6-12 Months - image 1 of 1
Fearless Lion Baby Costume

This little lion costume is the cutest!  I love the rainbow mane and tail. You could easily do a lions, tigers, and bears family costume with this one!

Baby Girls' Precious Pink Wabbit Costume - image 1 of 1
Baby Bunny Costume

This floppy eared bunny costume is just adorable.  It does kind of remind me of the pink bunny suit from A Christmas Story….but on a baby it is so much better! 

Baby Kangaroo Halloween Costume 0-6M - image 1 of 1
Baby Kangaroo Costume

I have always loved Kangaroos so much that it’s kinda a big part of my toddlers bedroom theme since I have so many!  I just love the baby kangaroo in the pouch which will keep baby entertained while wearing the costume too!

Mischievous Monkey Baby/Toddler Costume - image 1 of 1
Mischievous Monkey Baby Costume

The roly-poly belly and curly tail on this monkey costume is just adorable!  I like that it doesn’t have legs to fit baby into since that part of the costume can tend to run too big or small easily.  This looks like it would fit any size baby!

Hopefully you have found a great Halloween costume for your little one with these ideas!  I would love to see your baby costume ideas in the comments!

    That Panda costume! Why aren’t there more like that??? My youngest will be 5 months old for Halloween, and I think it would be perfect! My toddler… If he wore that monster costume, we’d never leave the house. Hahaha. He’s just point at himself and go “Ooooo” (because that’s what monsters say, obviously.)

      I know I have never seen baby costumes like that! I really think I will get the panda costume for my 5 month old to wear this year! The best costumes are ones that turn into everyday outfits and entertainment 🙂
