How to Choose the Best Toddler Underwear

The right underwear will help keep your toddler clean and comfortable without causing potty training stress. Let’s take a closer look at what qualities you should look for in toddler underwear, along with common differences between types of underwear that it can be helpful to keep in mind.

Qualities to Look For in Toddler Underwear

Here are the essential attributes to think about when it comes to toddler underwear.


Most toddler underwear comes from pure cotton, synthetic fibers like spandex, or a blend of natural and synthetic. Cotton is typically softer than synthetics, making it more comfortable and easier to pull up and down. Being able to maneuver the undies makes potty training a little less complicated for your toddler.

Cotton undies also offer better absorption than synthetic ones. As they potty train, toddlers will test the boundaries of how long they can hold their urine before visiting the bathroom, which can lead to leaks that cotton undies prevent from becoming messes. 

Generally, cotton underwear has more breathability, rendering them more comfortable for toddlers, although some synthetic fabrics claim to wick away moisture for better airflow. However, the synthetic fabric seems to hold onto stains, making it harder to reuse them.

On the plus side, synthetic underwear usually costs less than cotton and may provide a bit more stretch in the fit. 


Toddlers go through piles of underwear because of normal accidents and leaks that occur during potty training. That makes durability a primary consideration when shopping for underwear.

Ideally, toddler undies should hold up well to frequent washings. You need them to keep their shape without becoming baggy and unusable, especially in the leg openings. You also don’t want too much fabric thinning, which can create holes quickly.

Also, while it’s not crucial that the underwear maintains its pattern or color over time, it’s a pleasant benefit that can add value to your purchase.


Most toddlers won’t wear anything that causes them discomfort, so finding comfy undies they’re happy to wear is imperative. It can be the difference between getting out the door on time and being late for work because you had to wrestle with your tot to pull up a simple pair of underwear.

The Comfort level usually depends on the material and style or cut of the underwear. For example, cotton underwear provides softness and flexibility that many toddlers find cool and cozy. Or, boys may prefer either boxers or briefs because of the difference in leg design.

Seams around the legs and in the waistband also play a significant role in comfort. Seamless underwear works well for ultra-sensitive children, as do undies with seams sewn into the hem. Toddler underwear usually has comfier elastic waistbands to make pulling them up and down a quick process in comparison to the restrictive cinched waistbands found in diapers.  

Ultimately, comfort comes down to individual preference, even for toddlers, so it may take some trial and error to discover what your tike likes best.


If the underwear doesn’t fit properly, it’s pretty much useless, so size makes up another crucial consideration. If it’s too tight, it can cause irritation, but too loose and it won’t hold any leaks.

Toddler underwear comes in four primary sizes: 2T, 3T, 4T, and 5T. These sizes use height and weight to determine which one will be right for your toddler.

The height and weight may differ depending on the brand, so you should always double-check the company’s size chart to make sure you’re getting the right one. Some brands will also combine sizes for convenience, like 2T/3T. Underwear with combined sizes may have more stretch to meet a wider variety of measurements.


Although not the most critical concern, the design of the undies can make them more appealing to toddlers, making them more likely to wear underwear.

Toddler underwear is available in a variety of designs, from simple striped patterns to vibrant solids to popular cartoon characters. 

When you find just the right design, your toddler will be excited to wear the underwear, making your job that much easier.

Types of Toddler Underwear

Toddler undies may not come in as many styles as adult underwear, but there are still quite a few to choose from.

Training Pants

Training pants combine the absorbency of a diaper with the look and feel of regular underwear. They help keep messes to a minimum while still allowing the child to pull the pants up and down to use the toilet.

Training pants offer a slow transition from diapers to underwear for children who still need some help with accidents or feel uncomfortable jumping to “big kid” underwear too quickly.

Briefs are probably the most common option for toddler underwear. This versatile style is available in girls’ and boys’ patterns, offering softness and comfort without being too obstructive in movement. They come in many different materials, patterns, and sizes to help you find the right fit.

Because of the popularity of briefs, they have a wide price range, from very reasonable to high end.

Boxer Briefs

The boxer brief option works for boys who find standard leg openings in briefs too tight or uncomfortable. Since they extend down the leg, boxer briefs also provide a bit more protection from accidents. 

They come in a few different lengths, so you can choose the one your tot prefers.

Frequently Asked Questions

Still, have questions about toddler underwear? Check out our answers to these frequently asked questions.

Q: When Should My Toddler Start Wearing Underwear?

A: Once your tike is ready for potty training, it’s time for underwear. Most children will show signs of readiness between 18 and 24 months, while others may not start the process until three years old. 

Q: Should I Use Underwear or Training Pants?

A: Many parents and pediatricians recommend starting with training pants as a go-between when transitioning from diapers to underwear. These undies have better absorbency than regular underwear but are more cloth-like than ordinary diapers.

However, other experts feel training diapers aren’t necessary. Parents can transition directly from diapers to regular underwear, which helps with potty training because the child can feel when they’re wet. This discomfort discourages them from urinating in their underwear in the future.

Every toddler will have a slightly different potty training process, so it’s essential to stick with what works best for that particular child.
