When it comes time to find Halloween costumes for kids, you only get a couple of years where you have total control over what they wear. Embrace the baby stage, since you get to dress them up however you like, be it sweet, funny, silly, inspired by your favorite movie or TV show, standalone or part of a larger family Halloween costume.
That doesn't mean to say anything goes. There are lots of safety considerations to keep in mind when choosing a baby Halloween costume: The American Academy of Pediatrics advises parents to look for costumes that are made with flame-resistant materials, and to check to make sure they don't have accessories that can pinch or poke. At this age, you can skip the masks (you want to show off their sweet faces anyway), and you should check the costumes for loose strings or holes that can tangle or trap small fingers and toes. For those who are already mobile, make sure nothing hangs down that can tangle or trip them up, and check to make sure the hats won't slip down over their eyes.

Apart from the safety factors, there are convenience factors to keep in mind. How will you handle diaper changes? How tolerant will the baby be of the costume's different parts and accessories? (The fewer pieces — and the closest those pieces are to the clothes they wear every day — the better, we say.) Can you pack a similar backup outfit if any "tricks" come your way?
With all that in mind, these are the best baby Halloween costumes for 2024. Costumes based on food and "classic" Halloween iconography like pumpkins and ghosts continue to be popular, more so than the pop-culture-inspired Halloween costumes (though we have suggestions for those, too). Pick your favorite, and before you know it, you'll be on the hunt for toddler Halloween costumes.

What's more classic than a roly-poly baby dressing as a cute jack o'lantern for Halloween?

Pebbles from 'The Flintsones'

Thing 1 From 'The Cat in the Hat'
From here to there, from there to here, funny costumes are everywhere! Dr. Seuss fans can celebrate his zany world with this costume, which comes with a jumpsuit and hat.
