Dinosaur Baby Clothes & Onesies

Long ago, gigantic reptiles roamed the Earth and ate each other. Fortunately, all that’s left are fossils and these adorable dinosaur baby clothes. We’ve done our best to feature dino onesies for everyone. Whether you love science, 90’s fashion, scaly cuteness, or pop culture this selection of rompers will empty your bank account faster than you can say,
Micropachycephalosaurus.

Raawr Means I Love You Onesie

Raawr! That’s the sound that your baby will make – and you for that matter – at 3 in the morning. Feeding time, little dinosaur. This onesie is the perfect baby shower gift.


Babysaurus Jurassic Park Onesie

Hold onto your butts! It’s gonna be a bumpy ride. It’ll be worth it, though. Thankfully your baby will never grow teeth that are 9 inches long. THEN we’d be in trouble.


Brontosaurus Romper with Headband

If you like boho style baby clothes, this romper is it. Between the dangling pom poms, tiny headband and happy dinos, how can you say no?


Dinosaur Walks Onesie

Having a baby is definitely a commitment, but having a dinosaur as a pet might trump that. That’d be quite the long leash. Wouldn’t the dinosaur be walking your baby?


Newborn Dinosaurs

We love these little pastel hatchlings! Did you know that dinosaur eggs were thought to be 20 times heavier than chicken eggs?


Sleeveless Dino Jumpsuit

This one is perfect for the summer. The white background is bright and the miscellaneous dinosaurs are playful! Oh, and it has a zipper instead of snaps. How neat is that?


Boobivore Onesie

Besides it’s clever play on words, this onesie promotes normalizing breastfeeding. Nom nom nom.


Reading Dino

Reading to your baby builds listening, memory and vocabulary skills and is a great way to bond. When they’re older, you can read the long dinosaur names to them in silly voices and broaden their vocabulary even further.


Tacosaurus Onesie

We thought this design was incredibly clever…and delicious. T-Rex could bite off 500 pounds in one bite! How many tacos would that be? This onesie comes in a variety of colors.


Unstoppable T-Rex Onesie

Your baby is like T-Rex in more ways than one. Eating all the time, terrorizing the world that they live in, and limited by short, stubby arms. If you gave them a reacher grabber, who KNOWS what they’d get into?


Fossilized T-Rex Onesie

Remember the Night at the Museum movies? That’s what this onesie reminds me of. Thankfully, your little one isn’t going to roam the halls of the museum at night terrorizing the security guard.


Indominus Baby Onesie

This onesie is rad. Indominus Rex from Jurassic World was a T- Rex hybrid experiment gone horribly wrong. I’ll bet your baby will be just as good at camouflage, wreaking havoc and devouring food.


Ugly Christmas Rex Onesie

Re-live your ugly Christmas sweater childhood memories through your baby. They’ll be begging for a dinosaur for Christmas in just a few years. Merry Clawmas!


Stegosaurus Onesie

This simple Stegosaurus onesie has very vibrant colors, is handmade and super soft! This is a good baby shower gift for your favorite science enthusiast.


Dinosaur Space Onesie 2 Pack

Why did the dinosaur cross the road? To eat the chickens on the other side. This jumpsuit comes with a space-themed onesie as well.


Baby T-Rex Onesie

We did feature a hatchling snapsuit above, but this one was too cute not to include. Look at the polka dots on the egg and the broken shell on top of it’s head looks like a little crown. All hail baby T!


Lochness Monster Onesie

This original piece allows your imagination to run wild. Nessie’s vibrant colors and the little adventurer in the boat are the perfect example of the young mind and its creations.


Retro Dinosaur Onesie

We think this green T-Rex looks super retro on this neon pink backround. Your little one will totally be decked out like a 90’s baby while sporting a terrible lizard on their belly. Don’t worry, there are lots of other colors to choose from!


Cretaceous in Space Onesie

Meanwhile, in space…dinosaur meetups are occurring. Your baby can wear this onesie while you read them the children’s comic book series Dinosaurs in Space by Pranas T. Naujokaitis. You’ll thank us later.


T-Rex Costume Onesie

Dress your baby up like the Queen (or king) of the dinosaurs. This onesie comes in another shade of green as well. Terrifying Tyrannosaurus Toddler.


Godzilla Chaos Onesie

This is the perfect gift for your expectant friend or family member. Warn them of the chaos that’ll ensue once their little one enters Tokyo.


Fossilized Prehistoric Onesie

This onesie doubles as a way to teach your baby about each fossilized dinosaur. When your little one grows older, you can teach them the four different types of fossils: mold, cast, ichnofossils and true form.


Rexy and I know it Onesie

C’mon, this is precious. Your baby will be so fly in this king of the dinos snap suit. LMFAO wasn’t talking about babies in their song, but we can make an exception this time.


Marbled Dinosaur Onesie

Psychedelic colors, upside-down dinosaurs and a marbled design. Who wouldn’t want to dress their little one in this dandy one-piece? We wish this came in adult sizes!


Jurassic Park Quote Onesie

This classic Jurassic Park onesie comes in three different colors. We’ll let you decide whether this onesie is about tangling with the orders of nature or if it just means that your baby is indestructible. Your choice.


Long Sleeve T-Rex Onesie

We love T-Rex, can you tell? This duo is so colorful and menacing, your baby will look bad to the bone in this romper. It’s got long sleeves and comes in 3 different colors.


Nerdasaurus Onesie

Talk about a onesie that screams geeky baby! Bright colors, a fun design and a dinosaur wearing reading glasses. Not sure what the star is all about, but it’s cute right?


Dinosaur Baby Onesie

Straight out of the 90’s, Jim Henson’s Dinosaurs was a must watch TV show for all across America. The spoiled baby symbolized how parents turned a blind eye to kids at the time, thus robbing them of any discipline. If you’ve never seen it, check out a few episodes on Youtube.


Distressed Dinosaur Onesie

No, this T-Rex isn’t emotionally distressed, like you will be at 3am when your little one wants to be fed. We like this one because it looks like an array of constellations makeup the giant lizard’s silhouette.


Pterodactyl Onesie

Did you know that Pterodactyl’s aren’t actually dinosaurs? It’s true! Thankfully, your baby won’t be able to fly around and terrorize all their nursery animals while you’re sleeping.


Calvin and Hobbes

This Jurassic version of Calvin and Hobbes is really a creative idea. Rather than Calvin and Hobbes, we have Owen and his beloved raptor Blue. It doesn’t get much cuter than this.


Extra Terrestrial Rex

You can’t go wrong with a good ‘ole E.T. reference. The play on words that this onesie creates is genius. Your little genius will appreciate it one day as well.


Disco Unicorn Onesie

If you’re looking for a snapsuit that is going to give you strange looks in the grocery store, this is the one for you. What’s more interesting than a unicorn riding to the disco on the back of a triceratops? I’ll wait.


Bodacious Cretaceous

These boldly dressed dinos are totally rockin’, dude. Bill and Ted would be proud to dress their baby in this romper. What’s your excuse? The neon colors really make this eye-catching onesie one for the books.
