What you're buying, up close

Four details make it read as a dinosaur from across the room and still work on a wriggly baby.

A hood with teeth

White felt teeth, round eyes and a spike on top. The part everyone points at.

Spikes down the back

A row of soft fabric spikes runs from the hood to the tail in a darker shade.

A tail that bobs

Sewn on at the back, soft fleece all the way to the tip. It follows them everywhere.

Snaps for quick changes

Snaps across the crotch and elastic leg openings. Change a diaper without taking the dinosaur off.

See it on a real baby before you buy

Watch the whole routine first: snaps open, feet in, arms through, hood up.

Find the right size

Babies grow fast and this romper runs small. The surest way: compare with a romper that fits your baby today.

  1. Measure the length

    Lay a romper that fits now flat on a table. Measure from the top of the shoulder to the bottom of the crotch.

  2. Measure the chest

    Measure straight across, just under the armholes, then double it.

Measurements can vary by 1 in (2-3 cm). This romper runs one to two sizes small, so if you're between sizes, size up.

Dressing a wriggler, step by step

  1. Open the snaps

    Unsnap the crotch and lay the romper flat, hood at the top.

  2. Arms through first

    Slide it over a bodysuit, one armhole at a time. No sleeves to wrestle.

  3. Snap and check

    Close the snaps. Two fingers should slide under each leg elastic.

  4. Hood up, photo, hood down

    Pull the hood up for the shot, then back down so it stays clear of their face.

Is the Rawr Romper the right pick?

It's built for playtime, photos and dress-up. If you're shopping for pajamas, look for snug-fitting sleepwear, and you should hear that from us before you order.

Questions before you order

Still unsure about the size or the color? Message us. A real person replies within one business day.

Message us
Can my baby sleep in it?

No. It's made for awake time. For naps and bedtime, change into fitted sleepwear without a hood and lay your baby on their back in a crib with nothing else in it.

Does it work as a Halloween costume?

Yes. It's a one-piece baby dinosaur costume: a hood with felt teeth, spikes down the back and a tail, with no mask or face paint. On cold nights, layer a long-sleeve bodysuit and leggings under it and add a coat.

How does the sizing run?

Small, by one to two sizes. Compare measurement A with a romper that fits your baby now, or use the size finder. If you're between sizes, size up.

Is it warm enough for winter?

The fleece is warm, but the romper is sleeveless. Indoors, put it over a long-sleeve bodysuit. Outside, add a coat or a blanket like you normally would.

What is it made of?

Polyester polar fleece, with felt-style teeth and spikes sewn on.

How do I wash it?

Turn it inside out and wash cold on a gentle cycle. Hang to dry. Skip fabric softener so the fleece stays fluffy.

When will my order arrive?

Orders leave our warehouse in 1-3 business days. US delivery usually takes 5-11 business days after that, and you'll get a tracking link by email.

What if it doesn't fit?

Message us within 30 days of delivery. Rompers need to be unworn, unwashed and in their original packaging, and we'll arrange an exchange or a refund.

Is it a good gift?

It makes a fun baby shower or first-Halloween gift. If you don't know the baby's size, go one size up. They'll grow into it.

Small dinosaur. Big rawr.

Pick a color, size up if you're unsure, and get the camera ready.
