9 Baby Halloween Costumes for Your Baby’s First Halloween

In Costume Party Tips, Featured Articles, Onesies Planet by Caleb

Last Halloween, tiny babies in an Illinois NICU participated in the world’s cutest costume contest.

One of the most exciting parts of having a baby is celebrating their “firsts.” During their first year, this means their first Halloween costume.

Friends and family alike will be anxious to see what your little one goes as for their first trick or treat experience. Halloween will probably be one of your kid’s favorite holidays, after all, who doesn’t love free candy?

You want to make sure they start off on the right foot, or rather in the right costume. They might not remember the night, but the photos will last forever.

We love the idea of dressing our babies up as adorable lion cubs. Baby lion costumes have stood the test of time as a top baby costume for many years. Probably because they are just so cute!

This is one you can DIY, but we think you’ll get the most out of purchasing this one.  Or, if you simply want to choose from a wide variety of other options all at once, check out this link for a full host of warm, fleece and footed snuggly pajama costumes for infants to toddlers.

Similar to the baby lion, the baby bear costume is a solid choice.

There are few things cuter than a baby human dressed as a baby bear. Bear cub costumes will provide fuzzy warmth throughout Halloween night as temperatures drop.

Baby bunny costumes come in several different colors.

We have the classic blues and pinks if you are looking for traditional colors. For those who are looking to go outside the box, consider purchasing a bunny costume in a fun color, like purple.

If you have a baby girl, at some point she will probably want to go as a Disney princess.

A popular option for infants is Belle from Beauty and the Beast. We also love Elsa from Frozen and the Little Mermaid.

Dinosaur costumes will never go out of style. If you are dressing your first kid, this costume will make a great hand-me-down for your next one.

Baby monkey costumes are always a good choice. Your little monkey will look adorable dressed up as a literal monkey.

Keep a close eye on them though, as Halloween safety should be your top priority. 


Finally, if your little one is still an infant and can’t quite sit up on their own, we love this quirky corn on the cob costume.

Adding a little humor to the holiday will make it one to remember for years to come.
