Costco Baby Items: A New Parent's Guide to Diapers, Gear and Feeding Essentials

Becoming a new parent means stepping into a world filled with love, excitement and a whole lot of shopping lists. From diapers to bottles and everything in between, it can feel like there’s always something your little one needs. The good news? There’s one place that makes stocking up easier (and more affordable): Costco.

Costco has long been a favorite among parents for its unbeatable mix of value, convenience, and quality. Whether you’re prepping for your baby’s arrival or keeping up with their ever-changing needs, Costco offers a one-stop shop where you can grab trusted baby essentials all in one place.

Here’s how to make the most of your next Costco trip, what baby products to look out for, and why Bobbie stands out as a must-have for modern parents.

Why New Parents Love Shopping at Costco

For new parents, Costco is more than a grocery store; it’s a lifesaver. Here’s what makes the warehouse run worth it:

• Bulk savings that actually make sense: Babies have big needs (diapers, wipes, formula) that run out fast. Costco's larger pack sizes mean fewer last-minute store runs and bigger savings per item.

• Trusted brands under one roof: Parents rely on proven quality. Costco makes it easy by carrying a wide range of parent-approved brands (like Bobbie, Huggies, Honest and Gerber), ensuring everything meets your high standards.

• Consistency and reliability: Avoid the panic of "out of stock" signs for your baby's essentials. Costco’s robust inventory and bulk offerings help ensure that families can consistently find the products they need, exactly when they need them.

• The value of time: New parents don't have hours to spare between nap and feeding routines. Costco helps by simplifying the trip, allowing you to check off groceries, baby needs and household goods in one stop, with convenient online options available.

• Community and quality combined: Costco has a loyal following thanks to its focus on value and quality. It's reassuring for parents to know that every item meets Costco's strict quality standards. Add in perks like samples and friendly service, and it's easy to see why families rely on their membership.

How To Shop at Costco

Costco is a members-only club, so you'll need your own card to shop. Don't have one yet? No problem! You can join a friend or family member for a trip. Just remember: the member has to be with you to both enter and to check out, and they'll need to pay for your total purchase at the register.

If you're ready to join, Costco offers two membership tiers:

• Gold Star Membership ($60/year): Standard access to the warehouse and its low prices.

• Gold Star Executive Membership ($120/year): Includes all standard benefits plus an annual 2% Reward on most purchases. This check is sent yearly and can be used for shopping or redeemed for cash.

Top Baby Items to Grab at Costco

Making a Costco run? Here’s a look at some of the most popular and parent-approved baby products to keep an eye out for:

1. Feeding Supplies and Bobbie Formula

Whether you are exclusively formula feeding, combo feeding or prepping for pumping, Costco covers all the essential gear:

• Bottle Bundles: Bundles from trusted brands often offer a better cost per piece than standalone retailers, and are frequently available on Costco.com.

• Rotating Essentials: Items like silicone bibs, drying racks and sterilizer bags appear in seasonal rotations — stock up when you spot them!

• Bobbie Organic Infant Formula: The two-can bundle delivers European-style nutrition, Clean Label Project certification and shelf-stable peace of mind for parents who crave reliability without a subscription.

And now, Bobbie is available on warehouse shelves in select locations, in addition to online at Costco.com! Check our Store Locator to find Bobbie at a Costco near you. Whether in person or online, Costco currently offers a 2-pack of Bobbie Organic Original Infant Formula for just $37.99, offering more than $10 in savings compared to the usual $50 retail price.

2. Diapers and Wipes

Bulk diaper runs don't have to be overwhelming. Explore a few popular options to make your decision simple:

• Huggies Plus Little Snugglers: Offers dependable leak protection and a solid price advantage, often clocking in at roughly five cents less per diaper than online competitors.

• Kirkland Signature Diapers: Feature soft, plant-based materials and wetness indicators in every size. The everyday cost drops to an estimated 16–30 cents per diaper, according to Truly Mama.

• Kirkland’s Fragrance-Free Wipes: These wipes in warehouse quantities clock in around two cents each. They come in travel-friendly flip-top packs and skip chlorine, dyes and parabens, proving "budget" can still be baby-skin friendly.

• Huggies Natural Care Wipes: A great alternative for those who prefer a name brand but still want bulk pricing in one huge 1,024-count box.

When comparing bulk to grocery-store packs, remember the value isn't just the lower per-unit cost. You're also paying for fewer late-night emergency runs and a little extra peace of mind.

3. Baby Food and Snacks

Costco's shelves make it easy to build a clean and convenient pantry:

• Amara Yogurt Smoothie Melts: Comes in both single-serve packets and larger bags, perfect for travel days or an on-the-go snack.

• Kirkland Organic Puree Pouches: Deliver veggie blends with no artificial additives in a convenient 24-count variety pack.

• Everyday Snacks: Favorites like fresh berries, veggie straws, and other toddler snacks rotate through for daily use without soaring prices.

Choosing wisely is less about brand loyalty and more about checking ingredient lists. Focus on whole foods first, limited sugar and minimal processing to keep tiny tummies happy.

4. Baby Gear and Accessories

Larger baby purchases can stretch any budget, but Costco helps soften the blow with significant deals:

• Car Seats: Graco convertible car seats occasionally list for $20–$50 less than competing stores.

• Smart Monitors: Nanit and Owlet bundles surface online with valuable extras (like stands, travel cases or sleep sacks) rolled into the base price.

• Breast Pump Bundles: Medela and Elvie bundles often add sterilizer bags or milk collectors at no extra cost, maximizing value.

• Seasonal Gear: Strollers, highchairs and play yards rotate quickly. If something fits your registry list, act before inventory flips.

When sizing up baby gear, prioritize safety ratings, adjustability and easy cleanup. Then, weigh those factors against Costco’s generous return policy, which happily accepts baby items even after you've tried them at home. 

Tips and Tricks for Shopping for Baby Products at Costco

A Costco trip can feel like an adventure (especially with a baby in tow). But with a few simple strategies, you can make it smoother — and even fun:

• Plan your trips around your baby’s schedule: Try to visit during quieter hours (weekday mornings are gold). It’s easier to navigate the aisles and checkout lines when the store is less crowded.

• Check expiration dates on perishables: When buying formula or baby food in bulk, always double-check expiration dates. Bobbie, for example, has a clear “use by” date printed on every can so you can stock up confidently.

• Compare unit prices: Costco is known for value, but it’s still smart to compare unit prices. Look at the cost per ounce or per diaper — it’s often listed on the price tags to help you make informed decisions.

• Use Costco’s online store and app: Can’t make it to the warehouse? Costco’s online store has most of the same baby essentials available for delivery. That includes Bobbie formula, so you can order from your phone and have it delivered right to your door.

• Take advantage of seasonal deals: Costco rotates stock and offers seasonal savings throughout the year. Keep an eye out for discounts on baby gear or limited-time bundles on essentials like wipes and formula.

FAQs About Costco Baby Products

Is a membership required to buy baby items at Costco?

Yes, generally a membership is required to shop inside a Costco warehouse or to purchase most items online. There are a few exceptions, such as using a Costco Shop Card (a gift card purchased by a member) or buying certain prescription drugs at the pharmacy.

Can I buy small quantities of baby products, or is everything sold in bulk?

Most baby items are available in multi-packs, which is great for stocking up. However, Costco’s online store sometimes offers smaller quantities or bundles that are easier to manage.

Does Costco offer delivery for baby essentials?

Yes, they offer multiple delivery options:

• Same-Day Delivery: Available in most metro areas (via Instacart) for groceries and household essentials, including many baby items.

• 2-Day Delivery: Available nationwide for non-perishable food and household supplies, often with free shipping on orders over $75.

How often does Costco restock baby products both in-warehouse and online?

Costco warehouses typically receive daily shipments of products for restocking, but there's no set schedule for when a specific popular item will arrive. Online inventory is updated frequently, and you can often check a product page to see if it's available for local delivery.

Does Costco carry Bobbie formula in-store, or is it online only?

Bobbie is available in select Costco stores and via Costco.com. Grab a 2-pack of Bobbie Organic Original Infant Formula for just $37.99, or purchase it directly through the Bobbie website. You might even set up an easy subscription for reliable delivery!
