Especially designed to help relieve infant colic and gastroesophageal reflux.
Infant colic affects 3-28% of infants in Northern Europe and the UK.1 Researchers found that excessive intestinal gas could play a role. When babies drink from our new Natural Response bottle with AirFree Vent, they enjoy a teat full of milk, not air. Even when sitting more upright.
Our Natural Response bottle with AirFree Vent works to decrease the amount of air baby ingests by releasing the pressure that builds up in baby's mouth while drinking. This reduces the amount of air baby ingests and can help ease colic, spit up, gas and reflux – for a calm, issue- free feed.


Unlike conventional free-flow teats, our Natural Response teat is designed to work more like a breast. Natural Response adaptive technology allows babies to stop and pause – so they can enjoy a comfortable feed and follow their own natural suck- swallow- breathe rhythm.
Gastroesophageal reflux affects 40-60% of infants2. Our Natural Response teat allows for a secure latch, which reduces baby's air intake. And the AirFree Vent design keeps the teat full of milk (not air) even with the bottle horizontal, so baby can drink sitting more upright.


How does it work?
When babies drink from the breast, they have their own suck-swallow-breathe pattern. Our new Natural Response bottle and teat respects this natural way of drinking.
Inspired by mothers and babies, supported by you
AirFree Vent
The Natural Response bottle's AirFree Vent is designed to reduce colic and discomfort by sending air away from baby's tummy.


Air release
Because the AirFree Vent keeps the teat full of milk, the Natural Response bottle can be held horizontally, and baby can sit more upright while feeding.
Natural Response teat
Our new Natural Response teat works with AirFree Vent technology to support active drinking while locking milk in and keeping air out.

This is the best bottle I've had so far.
I decided to try the Anti-Colic bottle with AirFree vent from Philips Avent after becoming frustrated with all the bottles I had up to that point. Being a first-time mom, I wasn't sure which bottle to buy or why. I hadn't grasped the differences between bottles and the variations based on a baby's age. It was a learning process for me. Up to that point, I randomly purchased two glass bottles with the wrong lids for a newborn. A friend gave me another bottle from a well-known baby brand in the UK, and I received a whole set of bottles, including a breast pump, from my sister in Germany. These were from a reputable and expensive brand. Despite being designed to be similar to the breast with a good flow, my newborn struggled with them. The flow was too fast, and the lids alone had three different parts, making it complicated for me to reassemble them after sterilization. Then, I discovered the Philips Avent Anti-colic bottle with AirFree vent for Natural Response, and hurray! What a big difference! It arrived just in time when the baby was around 1.5 months old. Not only does this bottle look great and more luxurious than my other bottles, but it also made feeding times with the baby much more enjoyable. Until then, I didn't know what it meant to enjoy feeding my baby. I was still struggling to breastfeed directly, and using other bottles wasn't working well either. I was frustrated, wondering why everyone else seemed to find it easier to feed their babies. This bottle changed my perspective on bottles. Not only is it truly like the breast, but it also doesn't have hundreds of parts. It consists of only three parts plus the lid cover (the lid is almost just one part!). That's it! The parts are easy to clean and sterilize, and even easier to put back together for the next use. I no longer saw my baby coughing milk due to a too-quick flow, and feeding time became tear-free. Since discovering these Philips Avent bottles, I haven't looked back. The baby is now approaching 5 months old, and I've bought four more bottles with the correct flow for her age. Everyone in the baby massage group already knows about my Philips Avent bottle. That's how well it has worked for us. I highly recommend trying this bottle. I'm confident you won't regret it.
Pros
great design, looks attractive to the eye, looks more luxurious to other bottles, has a nice “aerodynamic” design, easy to clean and put back together, easy to carry everywhere around.
Cons
The only con I could give to that bottle is the fact that it is made out of plastic and will one day contribute to the already huge plastic pollution of fields and waters. I wish better alternatives will come out in the future, when it comes to the material of baby bottles.

The perfect Bottle for breastfed babies
I am overjoyed to share my incredibly positive experience with the Philips Avent Natural Flow bottles. As a parent, finding the right bottle can be a daunting task, but these bottles have been a game-changer for us. My daughter, who was previously resistant to bottles, embraced the Philips Avent with open arms. The unique design is a standout feature – the entire nipple fills with milk, ensuring a more natural and comfortable feeding experience while significantly reducing the intake of air. Having tried various anti-colic bottles that proved ineffective, discovering the Philips Avent was a breath of fresh air. The reduction in air swallowed has noticeably eased my daughter's discomfort, making feeding times a joy for both of us. What's even more impressive is the absence of nipple confusion. Transitioning between breast and bottle has been seamless, thanks to the thoughtful design of these bottles. Philips Avent Natural Flow bottles have truly exceeded my expectations, providing a reliable and enjoyable solution for feeding my precious one. I wholeheartedly recommend them to fellow parents seeking a superior bottle-feeding experience. I just wish I had found them earlier!
