Baby Halloween costumes are just the cutest, aren’t they? I had fun browsing around this summer, trying to come up with an idea for our October baby. With a due date in early October, I knew that we would be out and about with our little one by Halloween – but that with a less-than-one-month-old baby, we’d need to have a pretty simple, comfortable, and practical costume. I ended up deciding on a baby crayon! So cute, right? And with the zip-up footie PJs and crocheted hat, it’s pretty much the uniform of a newborn anyway. You can see the full post of how I made the baby crayon costume here!

In all of my Pinterest surfing for Halloween costume ideas for newborns, many of the baby costume ideas I came across were actually for older babies – like around 9 month and up, babies who could sit up or even toddle a bit. They had big fluffy tutus or crazy hats or other complicated clothing elements that just aren’t practical for a newborn. I was looking for costume ideas that would work for babies in the 0-3 month range, and still look cute on a sleeping baby strapped into a car seat. So as I was pinning away ideas for my own newborn baby, I decided to take my favorites and put them into one big blog post for you!

For you DIY-ers, if you’re looking to make a cute costume for your little one, check out Primary.com for solid colored short-sleeved and long-sleeved onesies, pants, leggings, zip-up sleepers, rompers, dresses, and more! They’re perfect for any costume you can dream up. (And they have big kid sizes for big brothers and sisters, too!)  No time to DIY? Etsy has some great options!
