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!

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.
