Review on Clear Tommee Tippee Anti-Colic Bottles, 5Oz, Pack Of 2 - Advanced Technology by Julia White

I like these bottles a lot and they are the only ones my son will consider (though I haven't found anything he'll take without some protest). They aren't compatible with any other bottles though, so if you get past the colicky gassy stage and want to be done with all the little parts, you have to buy new bottles. I also have the lids for transporting bottles, but I have to take the vent out of these to use them, so I end up having to store the vents or transport with the nipples instead of lids. And, I have a lot of trouble with these leaking around the collar (I think just because of all the parts and vents). Overall, if I had a choice, I would use the regular tommee tippee and skip the anti-collic, but since my little guy is pretty gassy, especially when bottle-fed, these are the best choice for now.
