I’m 54, and I’m shopping for a baby’s first Halloween again. The last time I did this, my phone had a flip lid. Okay, not quite, but close.
The baby isn’t here yet, so this year I’m shopping a little early and a little nervously. A couple of friends with newborns and a very patient Miniature Golden Retriever named Oakley gave me plenty of opinions on what works. Here’s what I’d actually buy.
What is the best type of Halloween costume for a baby?
The best baby Halloween costume is a soft, one-piece romper-style costume with no stiff masks, no loose buttons, and a stretchy neckline. Babies spend most of the night being carried, so comfort beats cleverness every time.
A few things I look for:
- Soft, breathable fabric. If it feels scratchy to my hand, it will feel worse on a baby.
- Easy diaper access. Snaps at the bottom matter more than the theme.
- No small parts that can come loose. Skip detachable buttons, glued-on eyes, and dangling pieces.
- Room for a layer underneath. Late October in Philadelphia can swing from 65 to 45 degrees in one evening.
What are the best baby Halloween costume ideas for 2026?
The most popular baby costumes are the easy ones: pumpkins, little animals, and simple cozy outfits. They photograph well and keep a baby comfortable.
Here are my favorites to look at:
- The classic pumpkin. A soft knit pumpkin romper with a stem hat is hard to beat. Browse baby pumpkin costumes on Amazon
- A cozy lion or bear. Hooded and fleece-lined, so it doubles as a warm layer. See baby animal costumes
- Philly pride. If you’re in Eagles country, a tiny green jersey romper counts as a costume in this city. I will not be taking questions on this.
- Dad-and-baby matching. If your baby is going as something silly, you can match. I’m still deciding if I’m brave enough.
How do you keep a baby warm on Halloween night?
Dress your baby in a snug base layer, add the costume on top, and bring a warm blanket or stroller cover for outdoor time. Babies can’t tell you when they’re cold, so check the back of the neck.
If the costume is thin, a long-sleeve bodysuit underneath does the job. Pair it with a warm hat and you’re set. A soft stroller blanket is one of those things you’ll use all winter, so it’s a smart buy even after the candy is gone.
What should my dog wear for Halloween?
Choose a simple, lightweight dog costume that doesn’t cover the face, restrict leg movement, or make your dog overheat. A bandana or a light pumpkin vest works better than a full-body outfit.
Oakley is not a costume dog by nature. He tolerates things for treats. For a Miniature Golden, I like:
- A seasonal bandana: low effort, zero fuss.
- A pumpkin vest that velcros on and off.
- A reflective collar light for the walk, since it gets dark early now. Check out LED dog collar lights
If your dog looks stressed, take the costume off. Photo done, move on.
Can you do a Halloween with a baby without trick-or-treating?
Yes. Many first-time parents skip door-to-door entirely and do a short evening outing or a photo session at home. A baby’s first Halloween is really for the parents anyway.
Here’s what I’d do in Philly:
- Put the baby in the costume, take your photos at home with good light, and call it a night.
- Walk a few blocks in a neighborhood like Fishtown or Northern Liberties, where stoops get decorated early.
- Head home for something warm to drink once the baby is down.
How much should I spend on a baby Halloween costume?
Plan on $15 to $35. Your baby will wear it for about an hour, so don’t overspend. Look for costumes that can double as a warm layer or cute everyday outfit.
Prime shopping events are mostly behind us, but costumes do go on sale as Halloween gets close. If you want to check what else I’m eyeing for the baby, I put together Best Newborn Baby Gear for Fall 2026
Dad take: this is the fun part
Everyone warns you about the hard parts of having a baby in your 50s: the sleep, the energy, the knees. Nobody talks enough about how much fun the small stuff is. A tiny pumpkin outfit. A dog giving me the side-eye in a bandana. That’s the stuff I’m looking forward to most.

FAQ
What size costume should I buy for a newborn? Buy one size up from your baby’s current size, since costumes often run snug and babies grow fast. Check the product’s age and weight chart.
Are Halloween costumes safe for babies? They can be, if they’re soft, flame-resistant, free of small parts, and don’t cover the face. Never put a baby to sleep in a costume.
When should I order Halloween costumes? Order at least a week ahead of October 31 to avoid shipping delays and sold-out sizes.
Can a baby’s first Halloween costume be reused? Yes. Pumpkin and animal costumes make good winter photo outfits, or hand-me-downs for friends.
