The Main Differences Between Dr. Brown vs Avent Bottles

Not all bottles are made the same and these two brands are no different. Here are the main differences between Dr. Brown vs Avent bottles.

  • Dr. Brown bottles operate on an internal vent system, this basically means that your baby gets less air in each gulp, leading to less gas and stomach upset. While the Avent bottles do not have this feeding system.
  • Avent bottles are slightly more expensive than the Dr. Brown bottles but only by a few dollars for four bottles.
  • Dr. Brown bottles can be tricky to clean as they have a few different pieces that have to be taken apart and you will require a very small brush, whereas Avent bottles are easier to wash and are also dishwasher friendly.

What Is So Great About Dr. Brown Bottles?

Most parents have heard of Dr. Brown bottles and only a few years ago, they were a huge breakthrough in baby’s bottles. Their bottles have a specially patented two-piece internal vent system that eliminates air and provides vacuum-free feeding.

This system helps to reduce air bubble oxidation of the milk and so essential vitamins are preserved.

By using this system it also ensures that your baby takes in less air when they’re feeding and so reducing the amount of gassiness and colic that they are suffering from.

What Is So Great About Avent Bottles?

Avent is a well-known brand that has been around for over 30 years and they were the first company to make bottles that were short with a wide neck. They were also the first company to produce teats from odorless and tasteless silicone. 

Avent bottles are super easy to clean with very few parts. Their nipples have a petal design that prevents nipple collapse and it also helps to promote a natural latch like your baby would have if they were breastfeeding.

They also have a great anti-colic system but do not have hundreds of different parts to clean.

Dr. Brown vs Avent – Our Choice

Both Dr. Brown and Avent bottles are fantastic bottles and each has its pros and cons. The choice that you make will also depend on the preference of your baby and if they are suffering from colic or excess gas. 

Dr. Brown bottles do just pip Avent at the post with their advanced anti-colic system that is proven to reduce colic and fussiness in infants. They are also slightly cheaper than the Avent bottles.

These benefits seem to put them on the top of the list for best bottles by parents. There is one drawback to them and that is that they truly are a pain to clean as they have so many parts.

But if it means that your baby is more comfortable and able to feed without pain and discomfort most parents will figure it out, they’re worth it.

The Final Thought

Like all baby products what works for one doesn’t necessarily work for another baby or parent for that matter. The question of if a bottle is good or bad does come down to your own personal experience with it.

Personally, I have used Avent bottles, they were great, never had any problems with them at all. They were super easy to clean and maintain. But I haven’t used Dr. Brown bottles but that doesn’t mean that they are a better or worse option for your baby. 

Do your research, talk to other moms about their experiences. Ultimately, you’ll have to find the bottle.

In fact, all other baby products that work for your baby and it does not necessarily mean that what you choose will be the top of every baby list. But does it really matter?
