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

I LOVE these bottles. I've tried every other brand out there. I mean that very literally.If your bottle leaks or nipple collapses it's super easy to fix. Because of the way these bottles are made you have to check the vent at the bottom of the insert peice. Pinch it to make sure it's not stuck together . This will keep the nipple from collapsing. Dishwashers especially cause the vent to stick together and not let air out.If your bottle is leaking. You CAN NOT heat up your bottle with the cap over the nipple. Just keep the cap off and all leaking should be cured :) good luck!
