Key takeaways

  • Bellababy offers six different breast pump models for breastfeeding moms expressing milk.
  • Bellababy has three hands-free wearable breast pumps with milk collectors and three models with feeding bottles and nipples.
  • Most top baby bottle brands can fit Bellababy pumps as long as they’re wide-necked and the mouth opening measures 2 inches in diameter.

What bottles are usually used with a Bellababy pump?

Bottles are provided with the double electric breast pump and pocket breast pump models. Milk collectors are used with hands-free wearable electric breast pumps. It’s recommended to stick with the pumps’ bottles for a smooth and leak-free pumping experience. As you might know, many bottles leak so the leaking issue can be a real problem.

However, if you’re using the MiniO Bellababy pump with bottle adaptors, check if other types of bottles such as anti-colic bottles (instead of using normal bottles) are compatible. 

Can you use all Bellababy pump models with different types of bottles?

Here’s part of the conversation I had with Bellababy’s support team.

Do Snappies bottles fit a Bellababy pump?

No, Snappies won’t fit any of the Bellababy pumps but you can use them as storage containers for milk pumped using the W38, W40. or W42 models. Bellababy E15 can take most breast milk storage bag brands as long as they have a zip opening which Snappies don’t have.

Do Evenflo bottles fit a Bellababy pump?

Even though Evenflo bottles are a popular choice for parents, there is no reliable information whether these bottles fit a Bellababy pump. However, any wide-neck bottle might be suitable. 

Do Dr. Brown’s bottles fit a Bellababy pump?

Dr. Brown’s wide-necked bottles fit the Bellababy breast pumps but if you want to be safe, rather use the MiniO model with its bottle adaptors. 


Is a Bellababy pump a good product?

Bellababy pumps are good quality and made with PP and food-grade silicone approved by the FDA. The products have undergone stringent testing to ensure they’re safe to use by breastfeeding mothers. 

How do you find a bottle compatible with a Bellababy pump?

The best way to find a bottle compatible with a Bellababy pump is to check with the manufacturer. Most wide-necked bottles fit Bellababy pumps as long as they measure 2 inches in diameter. 

What size is a Bellababy flange? 

Bellababy’s default flange size is 24mm however, you can purchase 17mm, 21mm, 27mm, and 28mm sizes separately. The E15 does come with 21mm, 24mm, and 27mm flanges. 


While most wide-neck bottles may fit Bellababy pumps, I recommend you double-check with the bottle seller before purchasing specifically for your pumping needs. 

If you’re exploring the pros and cons of silicone bottles, make sure they fit your Bellababy breast pump first! In case you’re considering other pumps, such as from Medela, I wrote about bottles compatible with this brand, or bottles fitting BabyBuddha pumps.

I’m Balint, founder of this site and a father (and dad) to a baby-turned toddler. I found the world of babies so fascinating that I started a blog dedicated only to that topic. By the way, I studied physics, engineering (PhD, MSc), and therefore I do a thorough research when I write about something. Since it’s a blog, of course I also write about my personal experiences.
