I really like these bottles in the sense of reducing the gasiness in my kids. But I don't like that when they're dropped hard enough or "thrown down" the disc in the bottom seems to move and they leak everywhere

I started out with a few different types of bottles for my daughter when she was born as I wasn't sure what she would take to. I started with 2 others then tried the Playtex VentAire and we had a winner. My daughter was colicy as well and these bottles worked great at reducing the amount of air she took in which is great with a colicy baby.

I have used theses bottles since the day my 7 month old was born, They say that they reduce gas, spit up and colic, my son still did spit up and have gas, but not near as much as most other kids in my family. I had a problem with one of the bottles, as when I boiled it, the numbers started coming off the outside of the bottle, I called Playtex and they were ever so helpful. I would definately recommend these bottles, as they were recommended to me.
