30+ Adorable Newborn Halloween Costume Ideas

The Best Newborn Baby Halloween Costumes

There’s nothing sweeter than a baby dressed up in a costume for their first Halloween! Here are 30+ affordable and adorable Halloween Costumes for babies in every budget.  

Well, it doesn’t need to be said again…but I will say it. I love Halloween!

Fortunately, Jack seems to be taking after me in that Halloween fun area, because he loves it, too. We’ve had so much fun getting out decorations, coming up with costume ideas, and just having fun scaring each other.

This is Oliver’s second Halloween, and while he doesn’t totally get what’s going on, he sure loves that you get candy sometimes. He also loves some of our interactive Halloween decorations around the house.

Two of my favorite Halloweens were Jack’s first Halloween, and Oliver’s first Halloween. There’s really just something so fun about seeing a tiny little baby in a silly or adorable costume.

With Jack, we dressed up as superheroes, and he was Jack Jack from the Incredibles. It was a hit!


With Oliver, he was only a month old, and only about six pounds. I can’t even believe it when I look back at pictures. Jack had been asking for our whole family to be Jack-o-Lanterns for MONTHS, so I agreed and made us all shirts.

Obviously, dressing a baby up for Halloween is mainly just for the fun of the family…but it sure makes for great pictures. If you can make a costume, it often will be a bit more affordable. However, I know most people with babies (especially newborns!) don’t have time to do that…and fortunately, Walmart.com has some of the CUTEST newborn Halloween costumes around.

Let me know which one is your favorite!

Infant Bunting Costumes

I’ll admit, I had NO idea what bunting was until I started writing this post. However, I started to see that there were many baby bunting costumes available on Walmart.com, and I realized it is actually quite the popular style for costumes.

Basically, it’s a bag that encases your whole baby and keeps them extra warm – which is why costume bunting bags are SO popular for babies! I mean, I don’t know about you, but where I live, you never know what the weather is going to be like on Halloween. I remember Trick-or-Treating on super warm evenings, and then I remember Halloweens where we had to wear thick winter coats over our costumes.

And these bunting bag costumes are TO DIE for. Some of them are so hilarious!
