Made for little days

No more costume meltdowns
Hats, headbands and tutus get yanked off in minutes. This is one soft flannel piece with the ears on the hood, so it zips on and stays on.

Sized by height, not guesswork
Each size lists length, sleeve, chest, shoulder and suggested height. Animal onesies often run short in arms and legs, so between sizes, go up.

Dress-up long after Halloween
The same costume zips on for photos, playdates, family visits and rainy-afternoon dress-up all winter.

Questions
Good to know
Which size should I choose?
Go by height, not age, using the size chart. These run short in arms and legs, so size up if your child is between sizes.
Can my child sleep in it?
No. It's a costume and playwear for awake, supervised wear, not sleepwear. Change into regular bedtime clothes before sleep.
Is it warm enough for outside?
The flannel is cozy for cool evening walks. On cold nights, add a coat on top.
Can my baby wear it in the car seat?
Dress at your destination if you can, and keep the hood down so nothing bunches behind baby's head.
What's the fabric?
Flannel in a cotton and polyester blend, with a front zipper and an animal hood.
How much is shipping?
Shipping is free on every order within the United States, with no minimum spend.
How long will my order take to arrive?
Orders are prepared in 1–2 business days. Most orders arrive within 2–4 weeks, and some items can take up to 30–60 days depending on the item, your location and busy seasons. Shopping for a shower or a due date? Please order early.
How do I track my order?
As soon as your order ships, we email you a tracking number. Tracking can pause for a while in transit, so a gap in updates doesn't mean your package is lost.
What is your return policy?
You can return items within 30 days of delivery if they are unused, unwashed and in their original packaging. Defective, damaged or wrong items are free to return. For change-of-mind returns, a $10 return shipping fee and a $10 restocking fee are deducted from your refund.
Is there anything I can't return?
For your baby's health and safety, we can't accept items that go in the mouth or against the skin once they've been opened, used or washed. Unopened items in sealed packaging can be returned as normal.
