With so many baby bottle brands available, it often becomes a struggle to find the right one for your baby’s feeding needs. Sometimes, it takes some experimenting with different brands before settling on your favorite one. If you’re down to choosing between Dr. Brown vs. Avent bottles, bottle warmers, sterilizers, you’ve come to the right place for more information.

When comparing the differences regarding the bottles, I picked Philip Avent bottles as the winner but it was a close tie! I also recommend Dr Brown’s Deluxe Bottle sterilizer as it fits all-size bottles. I also recommend Dr Brown’s bottle warmer because it also fits all bottle sizes and shapes. 

Dr Brown’s vs. Avent Bottles – Differences and Similarities

Anti-Colic / Gas

  • Dr. Brown’s: One stand out feature when comparing it with Avent anti-colic bottles is the unique anti-colic design of the Dr. Brown’s bottle. Both bottles offer colic and gas relief. But, Dr. Brown’s bottle’s internal venting system is geared towards reducing the intake of air, the main culprit for spit-ups, burping, and excessive gas which some babies with colic experience.  
  • Avent: The Avent bottles are designed to include an airflex valve in the nipple which vents air away from your baby’s tummy while feeding. This results in less build-up of gas while reducing other colicky symptoms such as burping and spit-ups. 

Leakage

  • Dr. Brown’s: it’s not unusual to hear of frustrated parents asking why their Dr. Brown’s bottles leak which is why some moms and dads stay away from this brand. However, the main reason for leaking Dr. Brown’s bottles lies in not using the venting system properly. 
  • Avent: Avent bottles may also leak if lids are not screwed on properly, the incorrect nipples are used, or the cap isn’t placed on the bottle when shaking the formula mix. But, these are some of the most common reasons for most bottle brands’ leaking issue and can be easily solved. 

Ease of Cleaning

  • Dr. Brown’s: Cleaning can be difficult because of the venting system made of many parts that need to be disassembled. However, the bottle itself can be easily cleaned with a bottle brush. 
  • Avent: These bottles are easier to clean with fewer parts to fiddle with. The wide-neck design also makes it easier to get into the bottle with a brush for hand cleaning. 

Nipples

  • Dr. Brown’s: Dr. Brown’s Original Nipples are engineered to ensure natural flow everytime your baby drinks. They’re constructed from silicone, making it easier for your baby to latch comfortably. 
  • Avent: The natural shape of the Philips Avent Natural Baby Bottle Nipple makes it easier to switch between breastfeeding and bottle feeding. The nipple is also designed to resemble the shape of mom’s breast, making it easier for your baby to latch when transitioning from breastfeeding. 

Dishwasher Safe?

Microwave Safe?

  • Dr. Brown’s: While Dr. Brown bottles can be placed in the microwave, it’s recommended not to use this method for warming milk. There’s the danger of hotspots forming which can scald your baby’s mouth. 
  • Avent: These bottles can be heated up in the microwave. However, only the container may go into the microwave without the screw lid, nipple, and cap. The manufacturers and food safety experts recommend stirring the content before feeding your baby to avoid hotspots. 

Material, e.g. BPA-free?

  • Dr. Brown’s: The plastic bottles are constructed with polypropylene materials that are BPA-free. The glass bottles are made of pharmaceutical-grade borosilicate glass that’s also free of BPA toxins. The nipples are constructed with silicone.
  • Avent: All bottles are 100% BPA-free and constructed with either polypropylene or polyethersulfone materials. The nipples are made with silicone and the AirFree vent insert is made with a combination of silicone and PBT. 

Recyclable

  • Dr. Brown’s: While older Dr. Brown’s bottles don’t have the recycling code on the bottom, the newer designs are recyclable. Check the code on the bottom of the bottle and toss into the correct recycling bin when you’re ready to discard the bottles.
  • Avent: All components of the Avent bottles are recyclable except for the nipples which are made with silicone. 

Expiry Date

  • Dr. Brown’s: These bottles’ expiry dates – none. However, you can look out for signs such as discoloration and cracks which indicate the material is disintegrating. Nipples should also be replaced every two to three months.
  • Avent: Expiration dates are not included on these bottles but as with Dr. Brown’s bottles it’s recommended to discard any b ottles that show signs of deterioration. The nipples should be replaced every three months.

Do Dr.Brown’s Nipples Fit Avent Bottles?

If you’re looking to replace the Avent nipples with a softer teat, use Dr. Brown’s nipples. Dr. Brown’s nipples are one of the only brands that fit Avent bottles comfortably. But, make sure you only use the wide-neck nipple size as Dr. Brown’s narrow-neck design doesn’t fit the wider Avent bottle neck.

Do Avent Teats Fit Dr. Brown Bottles?

While Avent teats may fit onto Dr. Brown’s bottles, they’ll interfere with the bottle’s venting system. This will negate the purpose of using Dr. Brown’s bottles for its anti-colic or gas features. It’s advisable to use only Dr. Brown’s nipples when using their bottles. 

Are Dr. Brown’s or Avent Bottles Better?

The two main differences between these bottles were the anti-colic design and the breast-shaped nipples. When it came down to deciding whether  Dr. Brown’s or Avent’s bottles are better, I chose Avent because of its ease of use when switching between breastfeeding and bottle feeding. 

The Avent nipple design also helps to reduce colic symptoms. I liked the ergonomic design of the bottle as well, making it easy for both the mom or baby to hold the bottle comfortably while feeding. 

If your baby suffers from serious colic and battles with excessive gas, spit-ups, or burps, Dr. Brown’s advanced venting system is your solution. This bottle is the winner if its anti-colic design is essential for your baby.

Dr Brown’s vs Avent Sterilizer – Differences and Similarities

When choosing between Dr. Brown’s vs. Avent sterilizer for sanitizing baby bottles, you’ll discover some distinct differences that will sway your decision. I’m comparing the popular Dr. Brown’s Deluxe Bottle Sterilizer with the Philips Avent Microwave Steam Sterilizer for Baby Bottles which is equally well-favored by parents. The top recommendation is the Dr. Brown Deluxe Bottle Sterilizer because it can fit more bottles compared to the Philips Avent sterilizer. 

Size and Fit

  • Dr. Brown’s: This sterilizer is big enough to hold up to six Dr. Brown bottles plus a range of accessories such as nipples, bottle parts, and pacifiers. The appliance measures 13.3 x 12.8 x 10 inches. Most leading bottle brands can fit into this sterilizer.
  • Avent: Measuring a compact 6.5 x 1 inches, this sterilizer can hold four Avent bottles or a combination of microwave-safe bottle parts, breast pump parts, and pacifiers. Other bottle brands can fit into this sterilizer. 

Convenience

  • Dr. Brown’s: The sterilizer needs to be plugged into an electrical source in order to operate. 
  • Avent: This sterilizer is designed to go into a microwave for quick and easy sanitizing of baby bottles and other baby products. It works very well for sterilizing breast pump parts quickly and efficiently. 

Ease of Use

  • Dr. Brown’s: User-friendly electronic controls make it easy to operate this sterilizer while selecting which cycle you want to use. A removable tray allows you to position the bottles so steam is directed straight into each bottle. A built-in accessory tray lets you place bottle parts, nipples, and other baby products, keeping them contained while being steamed clean. 
  • Avent: By adding water to the steamer and placing it in the microwave, there’s nothing complicated about using this sterilizer. You simply turn on the microwave and it  heats up the water for steaming to start.

Effective Sterilization

Does Dr. Brown’s Bottle Sterilizer Dry?

One of the main complaints of parents using Dr. Brown’s Bottle Sterilizer is that it doesn’t dry the bottles. This can become a problem when you want to use the bottles as soon as the steam cycle has been completed. Moisture build-up can also become a problem if the bottles aren’t removed immediately and placed on a drying rack to be air-dried.

Does Dr. Brown’s Sterilizer Fit Avent Bottles?

The Dr. Brown’s Sterilizer fits most popular baby bottle brands including the Avent bottles. You might be limited by the number of Avent bottles because of their wide-neck design but you’ll easily fit four bottles into this appliance.

Does the Avent Sterilizer Dry Bottles?

If the lid is kept on, the bottles will dry using the Avent sterilizer. Very little steam is left in the bottles at the end of the cycle so it doesn’t take long for them to dry out. 

Is the Avent Sterilizer Dishwasher Safe?

The Avent Microwave Steam Sterilizer can be placed in the dishwasher for easy and convenient cleaning. Don’t use detergents with harsh chemicals or abrasive agents as this will damage the steamer in the long run. 

Conclusion

I picked Philips Avent bottles as my top choice for its natural-like nipples.

 The Philips Avent Microwave Steam Sterilizer is popular with many parents and Dr, Brown’s Deluxe Bottle Warmer is my top choice as another accessory to consider. Which brand will you pick for your baby bottles and accessories?
