Easy Baby Costumes for Halloween

DIY Black Cat

For my oldest child’s first Halloween, he was a black cat and I donned a witch hat for the perfect low-stress Halloween costume. I already had the cat ears and tail, but here is a very similar set. Then all he needed was a black onesie and pants! Bonus: easy diaper changes.

Baby Tigers

These were my boys for my 2nd child’s first Halloween. I found these precious tiger costumes on Amazon. They were perfect to keep him warm and toasty while trick or treating.

Under the Sea

Looking for newborn halloween costumes? This creative baby’s first halloween costume works by incorporating a dressed up baby carrier and matching hat. We love this extra touch!

Says mom Sarah, ““under the sea” theme. My August baby was in a carrier so she was a seashell with a pearl on her head. My November girl was in a Etsy mermaid costume and a homemade mermaid princess crown.” This could also be a great one to add to a Little Mermaid family costume.

Says mom Danielle Lousie, “I wanted our son (1 yr) to be warm and comfortable for his first Halloween and I wanted to whole family to be apart of the costume without being the main Addams family characters. All he needed was a grey long sleeve onesie, a little hair gel and a black hypoallergenic eye liner for the mustache and eyebrows! Face make up for dad, matched with black shirt and pants, and a pair of shades and long hair for mom! Viola!”

Searching for a simple homemade costume? Take a peek at this adorable baby costume that incorporates the always popular children’s classic.

Says mom Allison, “I grabbed a lot of felt from the craft store and a book felt set from Amazon for my shirt. Traced the butterfly wings using a picture online with my projector, cut out the big pieces and used fabric glue to glue them together. Used the book as a reference to piece it all together and add colors. Added eyes and antennae to the hat and handmade the bag.”
