Sizing/Fit

Opinions on the fit of Kirkland diapers vary among parents. 

Some have raised concerns about the side tabs adhering too tightly to the diaper, which can result in tearing when making adjustments. 

Conversely, others have lauded Kirkland diapers for their excellent fit, accommodating both petite and larger babies comfortably. We recommend trying to see if the fit works for your baby! 

Type

Kirkland Signature Diapers from Costco are disposable diapers. 

As disposable diapers, this means that they are meant to be thrown away after each use. Some parents may prefer reusable, cloth diapers to be more sustainable! Unfortunately, Kirkland Signature Diapers from Costco does not offer cloth diapers. 

Color

As parents we love the designs on Kirkland diapers! They are colorful on the white diapers! 

They help make diaper changing time something to look forward to, especially as your child gets older. The designs on Kirkland diapers are random and not based on anything like Huggies brand diapers which usually sport Disney characters and graphics! 

Absorbency 

Kirkland diapers have excellent absorbency! We have tested all of their sized diapers and have came to the same conclusion: they can be relied upon for preventing leaks and blowouts! 

On average, Kirkland diapers, like many other high-quality diapers, are designed to hold approximately 18 to 32 fluid ounces (500 to 950 milliliters) of liquid, depending on the diaper size and style.

Ease of use 

The tabs on Kirkland diapers are a standout feature, as they strike the perfect balance between softness and tautness, securely fastening the diaper in place, even during the most active moments. 

Their softness and stretchiness make them a top choice for parents. Another feature is an extra soft breathable outer layer that is gentle on your baby’s delicate skin and prevents irritation. 

It’s clear that these diapers were designed with active and adventurous babies in mind, as they stay firmly in place during playtime, preventing sagging or loosening of tabs. 

For parents of lively little ones, Kirkland diapers offer a reliable solution to keep your baby comfortably dry and worry-free.

Waistband

Kirkland Signature diapers are in our top 3 softest waistbands on diapers that we have found, similar to the fit of your favorite sweatpants! 

Despite being stretchy, the waistband can comfortably support babies weighing 10+ pounds more than the recommended weight! Making Kirkland diapers a great choice throughout your baby’s first and second year! 

Wetness indicator 

The presence of a clever yellow stripe down the center of Kirkland diapers that transitions to blue when wet is a game-changer for parents.

 In those early months when your baby’s diaper patterns can be unpredictable, this wetness indicator is a lifesaver. It eliminates the guesswork, sparing you the effort of preparing for a diaper change prematurely, especially during outings or car rides. 

As your little one grows into their toddler years, you might have a better sense of when to expect a wet diaper every 2-3 hours, but having the wetness indicator as a backup is still a welcome convenience.

Quantity / subscriptions 

These diapers, like many products at warehouse retailers like Costco, are available in bulk, offering 132 diapers for size 6 and up to 192 for size 1 in each box. 

Buying in bulk has proven to be a convenient and cost-effective choice for my family, streamlining our shopping trips and simplifying our monthly budgeting. 

However, it’s essential to consider storage constraints if your home has limited space, as handling and storing over 150 diapers can become quite challenging.

Catering from newborns weighing as little as 8 pounds to toddlers of 35 pounds or more, they accommodate the changing sizes as your child grows.

Each Kirkland diaper comes with a unique moisture-absorbing gel that keeps your baby dry. This means you can put your baby to sleep without much concern about skin irritation or diaper leakage, even during the night.

Alongside this, a changing indicator strip – transitioning from yellow to blue when the diaper is wet – simplifies the task of knowing when it’s time for a fresh diaper.

Further, Kirkland diapers include a breathable outer layer and firm liner to help in reducing leaks. The fastening tabs are secure, ensuring the diaper stays in place even with active babies. The tabs’ effectiveness extends the lifespan of each diaper, contributing to the overall cost-effectiveness of this product range.
