I just recently went out shopping. I've had mixed experiences with baby bottles, mostly the "traditional" kind.....and really having to modify them to work properly. Yeah, I even tried buying the Nuk 5 bottle, which sucked too.
Anyways, I was just browsing around the store and came up on the expensive section of baby bottles. I figured, hey...I've got some cash, lets try a few of these. I bought a pack of Playtex Ventaire 8oz bottles, and OMG...these things work so freaking well. It's probably the most fun and enjoyable bottle I've ever used. Even for something designed for a baby, it worked flawlessly for me.
