There’s something absolutely magical about your baby’s first Halloween—or their second, or third! Watching those tiny hands reach for candy (that they can’t eat yet) and seeing strangers melt at the sight of your costumed little one creates memories that last a lifetime. But let’s be honest: choosing the perfect Halloween costumes for infants can feel overwhelming when you’re balancing adorability with safety, comfort with photo-worthiness, and your budget with your Pinterest dreams.
After reviewing countless options and considering what real parents need most, we’ve compiled the ultimate list of 20 Halloween costumes for infants that tick all the boxes. From classic characters that never go out of style to trendy pop culture references that’ll have everyone asking “where did you get that?”, these costumes prioritize your baby’s comfort while delivering maximum cuteness.
Safety First: What Every Parent Should Know
Easy movement and no small parts aren’t just nice-to-haves; they’re absolute essentials.
The best Halloween costumes for infants allow for natural crawling, rolling, and those adorable baby stretches without restriction. Look for soft fabrics, secure closures that won’t come undone during diaper changes, and designs that won’t interfere with car seat safety. Remember, if a costume has small buttons, detachable pieces, or anything that could pose a choking hazard, it’s not worth the risk—no matter how cute the photos might be.

Happy Halloween from our family to yours—may your trick-or-treating be safe, your photos be precious, and your baby’s first Halloween be everything you dreamed it would be.
