After spending lots of $$$, time researching, and hours upon hours rocking a gassy baby, the best bottle and nipple for my child is Nuk. The $4 bottle from Target. No fancy crap with 30 different parts and Dr.s names attached. She loved it. And she still nurses well from me. Problem solved.
Just a little PSA if you're having trouble with a bottle for your baby.
Re: Frustrated PSA: They've been around a long time for a reason.
Apparently Nuk was the trick for me when I was a baby also (according to my mom!).
It didn't work wonders for DD, but she won't take any bottles :-(
Glad you found something that worked!
