Halloween is one of the best holidays of the year. You get to dress up, eat tons of candy, and enjoy fun social get-togethers. Then you add a baby to the mix and the holiday instantly has a new sense of cuteness and joy. A baby’s first Halloween costume is something we parents (mainly us Mamas) spend too much time thinking about. Should the baby be a cute animal? Should I dress my baby for the weather vs. that adorable mermaid costume? Will this actually look like the picture on Pinterest? So many things to consider!
This post will make it super easy for you to find the best Halloween costume to dress your baby up in for parties or trick-or-treating. Themes include animal, princess, professional, and spooky Halloween costumes. The little owl, Sully from Monsters Inc., and Flounder are seriously adorable. There are also more simplistic options like “My First Halloween” or Disney-themed onesies. You can’t go wrong with either style.
Halloween with a newborn or baby is so much fun and I know these costumes and onesies will be perfect for making your family holidays memorable. Happy Halloween and have fun trick-or-treating!
