Review on 4-Pack Of Tommee Tippee Advanced Anti-Colic Bottles (9Oz) With Breast-Like Nipples And Revolutionary Anti-Colic Vent Design by Chelsea Williams

At around a month old we switched my baby from regular avent bottles to these tommee tippee's. Two months later and we are still going strong.Colic wise- my baby had pretty decent colic for weeks. He would arch his back and scream uncomfortably for 2-4 hours every night. After switching to the most expensive hypoallergenic formula without a lot of relief from screaming we were at our wits end with what to do. I tried these bottles on a whim and I am so glad I did. My baby was like night at day within the first bottle.I have questioned the need for these bottles a few times and tried to switch back to avent and it's always very clear that my son needs these.Cleaning/ease of use- these really aren't terrible to clean. I can usually clean and sterilize a set of 8 bottles in 15 minutes or less. It is more work than regular bottles but it is so worth it. Be sure to watch the demo video on tommee tippee's website showing you how to use and clean these.As other reviewers have pointed out, you must always make sure the air vent isnt sealed shut. This doesn't take much effort at all- I just pinch the star tip before placing the vent system into the bottle. I do still occasionally have issues with the nipples collapsing, but that is few and far between.
