13 Baby Essentials at Costco That'll Save You a Ton of Money

Get our top picks on baby products from Costco that make parenting a little easier (and more affordable).

Published June 21, 2023

The cost of baby items can really add up! But whether you're a first-time parent that needs all the stuff or you're replacing gear for a second (or third) child, there are ways to save.

Shopping at Costco is one of those ways to save that busy parents like us love - and we love these Coscto baby products! Here some top picks you may want to add to your shopping list.



Did you know that the average baby will require 2,500 to 3,000 diapers in their first year? That's a lot of money. The good news is that Costco has diapers for an exceptionally affordable price. Even better, you can choose from the classic Huggies brand or you can select the Kirkland diaper line, which is nearly half the price of those wholesale Huggies.

Need to Know

Every few months, Costco cuts the price of their diapers by over $10 per box. This is a great time to buy in bulk and save even more on these essential baby items.

Baby Wipes


Along with diapers, wipes are a must when it comes to baby care! Costco's Kirkland brand is a fantastic choice that comes in both scented and unscented.

More importantly, they are hypoallergenic, free of chlorine, dyes, alcohols, Parabens, or Pthalates, and they are made with natural plant fibers. We also love that this Costco baby item is ridiculously cheaper than competitor name brand wipes.

Diaper Genie Refills


Never has the quality of a trash bag been more important than when it is holding poopy diapers. Diaper Genies are the ultimate diaper disposal systems, but they require a certain type of bag. Costco offers customers over 1,000 bags for just over $20! They also throw in two carbon filters to further capture any stinky smells that might try to sneak out.

Baby Formula


New parents quickly learn that formula is another big-ticket item that babies need throughout their first year of life. Even after introducing solid foods, health experts still advise parents to make breastmilk or formula their baby's primary food source. Costco offers two types of Enfamil as well as Costco baby formula under the Kirkland Signature name. Some stores even sell Similac.

Need to Know

Once your baby turns one, they can graduate from formula to cow's milk. Parents also have the option of offering toddler drinks that are packed with vitamins and minerals to help round out their diets. Costco has you covered with both of these products.

Graco 4Ever Extend2Fit DLX 4-in-1 Car Seat


As the name implies, this car seat is all a parent needs to keep their child safe in the car from birth until they graduate to a big kid's seat! This Costco baby item can hold a baby as little as four pounds in the rear facing position and seamlessly transition all the way to a backless booster for kids up to 120 pounds.

Most importantly, it "meets or exceeds the child restraint criteria for a frontal crash test under the US FMVSS 213" and it will last for up to 10 years.

It's also extremely easy to install and adjust over time - I own two of these car seats and would highly recommend them.

Need to Know

The National Highway Traffic Safety Administration notes kids cannot sit in a regular car seat until they are an average of eight years of age. This makes this car seat a sound investment that will keep your child safe until you no longer need it.

Baby Monitors


In a few short months when your baby moves to the nursery, a baby monitor will give you peace of mind that your little one is doing well throughout the night. Another one of the top Costco baby items to snag is a baby monitor.

Not only do they offer exceptional prices, but they also give parents the choice of some premiere brands like Owlet, VTech, and LeapFrog.

All Free & Clear


Hypoallergenic, gentle on sensitive skin, free of fragrances and dyes, and tough on hard messes: this laundry detergent is a great choice for your baby's clothes. You can buy it for a fraction of the cost at Costco, making it another top buy on our Costco baby product list!

Fruit & Vegetable Pouches


Most parents recognize the Gerber brand, but it comes at a high cost. Kirkland makes a delicious spread of fruit and vegetable pouches that are not only healthy for babies, but are also something that the rest of the family can enjoy as well. Best of all, they are less than 65 cents per pouch! That is less than half the cost of the Gerber pouches you can purchase at other stores.

Fast Fact

Did we also mention that these pouches are organic, gluten free, have no added sugars, and only contain ingredients you will recognize? Sounds like a win to us.

Baby Books


It's never too early to start reading to your baby and Costco has an amazing collection of baby books to choose from. Some of these include The First 100 Library, The Rainbow Fish Little Library, and My First Science Library for Babies.

Baby Clothes


It is amazing how many outfit changes one little person can go through in a single year. Make sure your sweet baby is always looking their best by snagging baby clothes while shopping at this big box store.

While clothing is probably the last thing that you would think to buy here, Costco carries recognizable brands like Disney and Carter's as well as other great clothing lines by Kid's Headquarters and Koala Baby. And, of course, since it is a buy in bulk store, you can expect that all of their baby gear comes in a set for a great price.

Puppy Pads


It would be great to have that adorable nursery set with the matching linens covering the crib and the changing table pad. Unfortunately, babies are messy little creatures, especially when there is tummy trouble afoot. This makes puppy pads one of the most underrated baby items that parents can buy.

Simply line the changing pad with the puppy pad and use it until it gets dirty. No matter if you have a blowout or a little boy who tends to go when he is uncovered, this is a great way to cut back on your neverending pile of laundry!

Helpful Hack

Puppy pads are also fantastic for on the go! They are great for lining the not-so-clean changing tables in public restrooms or any other surface that may turn into a makeshift diaper change spot.

Educational Play Rugs


As soon as your baby starts to move, they will spend the majority of their time on the floor. Play mats are a wonderful way to protect their little knees and give them a comfortable place to play.

Costco sells three slip-resistant Smithsonian Area Rugs that are not only large, but also educational! Choose from options like a map of the United States, an alphabet mat, and a space-themed rug.

Infant and Children's Tylenol and Motrin


When your sweet little one gets sick, Tylenol and Motrin are a must for helping to control their temperature. These Costco baby products are always good to have on hand because you never know when to expect a sudden fever.

Fast Fact

Infant and Children's Tylenol are exactly the same. Both contain 160 mg of acetaminophen per 5 mL of liquid. The only difference-one comes with a syringe and the other a medicine cup. Save your money! Buy the Children's product and then snag a syringe at the pharmacy.

IMPORTANT NOTE: Motrin Infant and Children's medications are NOT the same, so the advice above does not apply to this Motrin.

Buying Costco Baby Items Helps Parents Save


Costco baby products are a great investment for the parents looking to save money (and avoid going to the store every few days). For those folks who are considering an executive membership with this store, you can easily pay for your upgrade with the amount you will spend on baby products.

Yes, that's right - this level of membership gets you 2% cash back on every qualifying purchase. If you spend $3000, you will make up the money you spent to upgrade the membership. Diapers alone are $40 to $50+ a box. It doesn't take a mathematician to see the savings potential.
