I have a 4 month old baby and i'm planning to buy baby bottles for his supplement formula. I want a bottle that will fit snugly to his mouth and prevent colic. I've searched the internet and I found this buzz about BPA, the National Institutes of Health concluded there were concerns about the effect of BPA on the brain, behavior, and reproductive system of fetuses, infants, and children at current exposures. I also found a list of interesting baby bottles that is BPA free, among the list are Avent, Evenflo, and Gerber. I can't decide on which bottle to buy because all of them claims that their brand is better. What Baby bottle are you using? What baby bottles do you think are the best?
