The first Halloween with a baby is mostly a photo and a very early bedtime, and that is exactly the point. We have done this a few times now between us, and every year the plan gets simpler: one costume that feels like pajamas, pajamas that do the whole month, a photo before anyone melts down, and a trick or treat route that ends at your own front door. Here is the version we would hand a friend, with the pieces we actually reach for.
Pick a costume they will keep on
The costume that wins is the one that feels like clothes. Soft fabric, a real zipper or snaps, nothing tight at the neck, nothing that has to stay on the head. Babies under one do not need a costume at all, a printed romper counts. From about a year up, a one piece jumpsuit with a hat that can come off in ten seconds is the sweet spot, because it goes on in one move and there is nothing to lose in the car.
Our favorite for toddlers is a safari explorer jumpsuit that is made to order with your child's name embroidered on the chest. You pick a collar patch, add a name on the back if you like, and choose a hat with little ears. It reads as a costume from across the street and as a soft playsuit up close, which is why it keeps coming out in November for pretend play.
For kids who have a strong opinion by now, a knight tunic with a cape is easy to get on over a long sleeve shirt, and the cape is the part they care about. Fairy dress and wings sets work the same way for the princess crowd.
Two rules we keep every year: no masks for babies and toddlers, face paint is fine, and no bulky costume under a car seat harness. Dress them in the costume, buckle them in their normal clothes, and change at the party. It takes five minutes and it is the safe way.
The pajama route, for Halloween all October
If your baby is too small for a costume, or you simply do not want to fight one, Halloween pajamas are the answer. They get worn every night for a month, they photograph beautifully at the pumpkin patch, and there is no last minute panic on the 31st. Bamboo zippies are our pick for the littlest ones because they stretch, they are cool enough for a warm October and the double zipper makes the 2am change quick.
For daytime, a pumpkin and ghost zip romper does both jobs: it is the outfit for the pumpkin patch and it is the costume if you never get around to one.

Shop HalloweenThe photo you will actually keep
Take it early in the day, before the nap, in the outfit they are already wearing. Natural light by a window beats every porch photo at dusk. For a first Halloween, a simple bodysuit that says so does the job, and it becomes the photo you compare every year after.
If you want one keepsake, a personalized ghost blanket with your baby's name works in the photo, on the stroller for the cold walk, and on the couch for the movie night after. And if you want to be in the photo too, matching pajamas for mama and little one are the low effort way to do it.
A trick or treat plan for babies and toddlers
Keep it small and keep it early. Go while it is still light, do a few houses or one friendly street, and bring the stroller even if they insist on walking, because they will stop insisting three houses in. Layer a warm bodysuit under the costume rather than a coat over it, so the costume still shows and nobody overheats on the walk back.
Give your toddler a bucket to carry. It is the part they remember, and it keeps their hands busy while you handle the doorbell talk. A soft fabric bucket is light enough for a two year old and it comes back out next year.
The candy: sort it before anyone digs in. Hard candies, gum, nuts and anything small and round are choking hazards for children under four. Most toddlers are perfectly happy with one soft treat and the job of handing the rest to you. For babies, the sensory version is more fun anyway: a stuffed pumpkin with a few crinkly toys inside is the whole party.
Safety checklist, the short version
- Costume fabric should be labeled flame resistant, and keep it well away from jack o lantern candles. Battery tea lights are easier anyway.
- No masks for babies and toddlers. Face paint or a hat that comes off easily.
- Nothing small enough to pull off and mouth: check buttons, sequins and glued on pieces before the first wear.
- Reflective tape on the stroller and a small light on the bucket if you are out after dark.
- Costume off, normal clothes on, before the car seat harness.
- Bedtime is bedtime. An overtired toddler in a lion suit is still an overtired toddler.
When to order
Made to order pieces like the personalized costume and the name blanket are embroidered after you order, so the first half of October is the comfortable window. Ready to ship rompers, pajamas and buckets can wait until the last week, but sizes go first in the popular prints, so if you have a favorite, take it when you see it. Everything in this guide ships free in the US on orders over $100.

Frequently Asked Questions
What age can a baby wear a Halloween costume?
Any age, as long as the costume is soft, breathable and has nothing near the face. For newborns and young babies, a printed romper or sleeper is the costume. Save hats, capes and full outfits for babies who sit up and tolerate them, and skip masks entirely for babies and toddlers.
How do I keep a toddler's costume on?
Pick something that feels like clothes. Jumpsuits and one piece costumes with a real zipper or snaps stay on far better than layered pieces with ties. Let them wear it around the house a few times before Halloween so it feels familiar, and put the hat on last, in the driveway.
When should I order a personalized costume?
Made to order pieces are embroidered after you order and then shipped, so give them the first half of October. Ready to ship rompers and pajamas can wait until the week before.
Can I trick or treat with a baby?
Yes, in a small dose. Go early while it is still light, keep it to a few houses or one street, and bring the stroller so you can head home the moment the mood changes. The candy is for the grown ups this year, which nobody minds.
Is candy safe for toddlers?
Hard candies, gum, nuts and whole grapes are choking hazards for children under four, so sort the bucket before anyone digs in. Most toddlers are perfectly happy carrying the bucket and handing out the candy to you.
One more thing, from us
Nobody remembers whether the costume was perfect. They remember the tiny person in the lion suit falling asleep on the walk home. Keep it soft, keep it short, take the photo early, and enjoy it. Happy Halloween from all of us at Moogco Baby.
