When was the last time you had the milk leaking between the plastic ring and bottle? You are wondering why sometimes it leaks, and at times it doesn't. Twisting it tightly or loosening it doesn't help. You have searched Avent website, and asked around 'is there a special way' in using Avent feeding bottle, other than putting the nipple, plastic ring and bottle together. Well, I think I have the answer for you.
When I first started feeding my son, I had the same exact problem. It left me in confusion as to why it leaks sometimes. Instead of feeling frustrated, the 'mysterious' leak got me really curious.
The Avent bottle nipple has three air valves near the base of the nipple. As we all know the valve lets air into the bottle to prevent any vacuum build-up.
Alright, now take a look at the plastic ring. If you look closely, there are four sets of fins around the plastic ring.
Now you just need to place and align the nipple with at least two of the air valves within the fins before putting it together. Voila! That's it no more leaks!
Take note, if you twist it too tight the valves won't work properly and therefore creating a vacuum in the bottle and milk won't flow out that easily. I can't tell you how tight is tight enough for you, so some trial and error is needed. Or you might want to checkout my method here. I'd like to add that over tightening it will affect the alignment ( credits and thanks to 'adhis' for her tip ).
Despite this, my wife and I still use Avent bottles and in fact we've bought over 18 bottles to date and still using it for our little baby girl. Avent feeding bottles is still one the best bottles around.
So I hope this little trick helped you, and happy feeding! :)

ps. I have seen some sites and blogs posting up my method, I'd appreciate it if you give credit where it's due, that's all I ask =).

Avent has started selling a newer version of the Avent BPA free bottles more than a month ago. This new bottle has an extra blue/white ring and it's anti-colic system is a two piece system ( instead of one-piece originally ). People who bought these did not experience any leaks. Checkout the 9oz dual pack on Amazon.com.
Life saver thank you very much. If I know where you live I will buy you a beer :-)
ReplyDeleteThank you thank you for this! I use the newer style, and they still leak like crazy sometimes and not at all at others--this trick seems to have solved the mystery! They're great bottles otherwise, so I appreciate your posting this years ago--still good advice. :)
ReplyDeleteTHANK YOU! I'll try it!
ReplyDeleteNot sure if anyone still read this actively. I bought Avent teats recently and realized that they changed the vent grooves. It does not look like those in the picture any more. It has 3 vent grooves instead of 6. I am not sure why the change. Probably to fix the leak. No documentation on that. Google it and found no result. Anyone knows about this? I am afraid if the new design allows less air into the bottle and hence less effect on the anti-colic.
ReplyDeleteAVENT are awful. They make a mess. I purchased a product and I expect it to work. We returned them all. Awful product.
ReplyDeleteReferring to the change in teat base ventilation groove, here is the reply from Avent:
ReplyDelete"The change in the vents does not affect the flow from the teats. The change was made to reduce the level of leakage should the teat leak in use."
This works. Crunchy you are a genius. Thank you !!!!!!!! my floors are no longer sticky. :)
ReplyDeletethank you so much for this wonderful tip. I'm a FTM and was close to being discouraged with Avent after reading so many leaking problems and wanted to just buy the new Tommee Tippee. well i guess i'll try it first since my first choice was really Avent ;)
ReplyDeleteI am SO thankful to find this information!! :) I was at my wits end, ready to throw them out!! Now I don't have to.
ReplyDeleteHi, i read you solution to the problem but can't understand why it was needed to separate that ring from the bottle. Couldn't they produce it being fixed to the bottle or the nipple? I woke up at nite to feed the baby and forgot to put that righ on. I was getting crazy as I could not understand why it doesn't stop leaking. Then i tried 3 different nipples but it didn't help. In the morning I understood that a righ was missing and it annoyed me even more. Why was it important to separate the ring from the bottle? Is it possible to use it without a ring and have no leaking? What is level 2 or level 3 nipple? I do not know which level I have...
ReplyDeleteI do not see my comment on why the ring is separated from the bottle. Please email me the answer to my address if possible- furfreiheit@rambler.ru. Thank you
ReplyDeleteplease answer this question. Why the ring in Avent bottles separates from the bottle? Do they want us to lose the rings to buy new ones? Is it a source of making additional money? To me it seems easier to buy other brand bottles than fight against leakage, look for a ring if it is removed from the bottle when washed etc. This is a headache!
ReplyDeletewhere is my comment??
ReplyDeleteHey, will a person who is so much thanked answer the above mentioned questions regarding Avent bottle rings?
ReplyDeletethank you. just started using avent and had the same problem. sometimes leaking and sometimes not. now it is over.
ReplyDeleteThanks for the tips, very useful...problem sorted!
ReplyDeleteOnly variable flow teats have air flow indecations on the bottom normal teats don't so how can I line them up when there's no marks ?

ReplyDeleteTurns out my issue was accidentally ordering Natural nipples to use with a Classic+ bottle. Of course they fit and look correct but leak every time. Switched the ring out to use a Natural ring and BAM, no more problem.
ReplyDeleteAwesome Blog! its very interestingly and informative in reading. This is really a great Stuff for sharing. Keep it up. Thanks for sharing.

I read that if the nipple flow is incorrect, your little one can blow too much air in because they're struggling to suck. This causes too much pressure.
ReplyDeleteI have no idea if this is actually what the issue is, but going up a size helped for me as well.
Only trying to spread correct information, hope this helps!!!
