Buying Guide for Toddler Onesies


Toddlers can be pretty fussy, and if you purchase a onesie that isn’t comfortable, they won’t wear it. For onesies, comfort really comes down to two things – sizing and material.

When it comes to sizing, it’s best to go for a onesie that’s a size or two larger than needed. This will ensure comfort as well as provide better value as it will fit them for longer.

For materials, 100% cotton is the way to going – avoid anything with synthetic materials, such as polyester blends, as they are more likely to irritate the skin. This is true not just for onesies, but also for other kids dino clothing items for use around the house, like toddler dinosaur slippers, dressing gowns, or dinosaur bath robes for toddlers.


Almost all toddler onesies are made from 100% cotton. There is good reason for this choice, cotton is light, breathable and non-allergenic, making it ideal for sensitive skin.

That said, you may come across other materials, such as polyester blends. However, it’s generally best to avoid these, as they can be uncomfortable and may irritate your child’s skin, making them uncomfortable to wear.

Always make sure to check the material before placing an order, as getting one that is comfortable is key. This is both to protect your little one’s skin and to ensure that they’ll happily wear it.

Size and fit

Toddler onesies don’t need to fit as snugly as they do for babies or like other clothing items, such as dinosaur pajamas for toddlers. This makes it perfectly fine to buy one that’s a size or even two sizes larger than your little one’s current size. This is great news for parents, as it means they’ll last longer than other clothing for kids of this age.   

It’s also important to note that with onesies, sizing tends to be less consistent than with other clothing. Some manufacturers option for increments of 6 months like baby clothing, while others offer them in aged sizes.

This can make getting the right size challenging. Be sure to check reviews and comments from verified buyers before parting with your money. This is to ensure that you get one in the right size range for your child.  


As any parent of young children knows, they have a natural knack to attracting mess. Whether it’s paint, colored pens, food, or indeed anything else, little kids are stain magnets. This makes getting a onesie that’s easy to clean essential.

Typically, you’ll find ones of two types of washing instructions – machine and hand washable. It’s best to avoid hand washable onesies, as these will obviously be a lot more work. Machine washable is always the way to go when it comes to cleaning.

Final thoughts

Onesies are a great addition to your toddler’s wardrobe, adding variety and convenience to their selection of clothing. Provided you follow our guide, onesies are comfortable, fun and safe. This makes them great for playtime, fancy dress or just roaming around the house or yard.

When picking one out, stick to cotton – this material is breathable, soft and non-allergenic. These factors combine to ensure that your child is comfortable, safe, and will love putting and keeping it on without fuss.

They also don’t need to cost the earth, as our list demonstrates. There are loads of great toddler dinosaur onesies available at a low-price point, south of $30, offering great value. Also, make sure to purchase one a size or two larger than needed. This ensures you’ll get the most out of a onesie, as they don’t need to be as snug as rompers.

Well there you have it, our buying guide and list of the best dinosaur onesies for toddlers. We hope that you found it useful and that you now know everything you need to pick out one that’s perfect for your little one.
