Loveable Lion

Dress your baby girl or boy as a cute little lion cub. It could be for a themed animal party, or even a Disney party. We all love the Disney classic, The Lion King.

This Baby Loveable Lion Costume is extremely snug and will provide great comfort for your baby, so you don’t need to worry about them getting irritated or uncomfortable. If your little one gets tired and wants a little nap, we’ve got you covered! The lion’s mane wraps around their head like a cushion, so they can fall asleep comfortably.

It’s always good to teach our littles ones the importance of healthy eating from a very young age. So, what better way than to transform your bundle of joy into an avocado? You may have a themed party coming up, where you want to bring your baby along, or even just to make them look extra sweet at home. Everyone will want to be the first in the queue to avocuddle with your baby – first come, first served!Avocuddles Baby Costume


Baby Penguin

Penguins are an all-round cute and friendly animal. Children are a big fan of penguins, with the Happy Feet film and all-time children’s classic TV programme, Pingu being one of the most watched series. This Baby Penguin Costume isn’t like any ordinary penguin costume, as it has its own very top hat, which is attached onto the hood of the outfit. Your baby will look adorable! It also has oversized flippers and arms for that awkward penguin appearance. You’ll have everyone saying ‘awww’ when they pass by and catch a glimpse of baby Pingu.Baby Penguin Costume


Panda Bear

Pandas are part of the bear family and they sure love to hug trees! Very similar to the beloved Po in the movie, Kung Fu Panda, our Baby Panda Bear Costume is so enchanting and will have everyone wanting a hold! If you have an animal-themed party coming up then this is a great idea for you. Halloween and World Book Day are also times of the year where this can be worn too. Go and have a stu-pand-ous time with the little one!  Baby Panda Costume

Baby Mouse

When we think of mice, we lay down a mousetrap and a bit of cheese to capture them – we surely don’t want any running around in the house after our food! Some mice are very cute though, especially this one, which is far from vermin. Just remember the days of Tom and his mate Jerry, and also Danger Mouse - mice can be good guys too! A novelty mouse costume is a great baby costume idea for little ones that have a cheeky smile. Baby Mouse Costume

Precious Puppy

There’s always something extra special between a baby and a dog’s bond. Give your baby a make-over and transform them into a loveable puppy, in this Precious Puppy Costume. The big, brown, floppy ears really make this outfit even cuter and will have your friends and family members stroking them, as if they were a real pup! It’s a great choice for any animal-theme party or playtime at home. Baby Precious Puppy Costume

Dinky Dino

Dinosaurs can be quite big and scary, but your baby will be nothing but adorable in this Dinky Dino Costume. It’s perfect for any occasion, whether that’s an animal or a Disney themed party. You can even re-create the Dino from Disney’s ‘The Good Dinosaur.’ Our favourite thing about this onesie is the dino’s head, with its big eyes and teeth. Your baby’s smile will peak through. Grrrrr! Baby Dinky Dino Costume

Tiny Turtle

We all remember the Disney film, Finding Nemo. Squirt is the son of Crush, the cool-eccentric turtle that helps Nemo and friends find their way to his dad. Turtles are fascinating creatures, and you can transform your baby into one, in this Tiny Turtle Costume. It’s a great baby costume idea for a Disney party, or even an ‘under the sea’ party. No one will be able to miss your baby as a turtle, with its brightly green coloured outfit and realistic turtle shell. A top baby outfit choice for little ones that love the water! Baby Tiny Turtle Costume

Business Baby

Most babies prefer to eat, play and sleep to their hearts content, whereas some like to hustle at a young age and see what mama and papa get up to at work. Your little one will look the part in this Baby Gangster Costume. They’ll be ready to take on all the work in the family business so you as parents can sit back and relax! It’s also an adorable costume to wear for a 1920’s themed party you have coming up. The business hat is a cute addition to the outfit and will have them looking like a real mobster boss! Baby Gangster Costume
