Re: Dr. Browns bottles
When our baby was a preemie we used the small evenflo glass 4oz bottles with a basic nipple on them. We then moved to the Born Free bottles. We had some Dr. Brown's but once our baby tried the wide mouth of the Born Frees she never went back.
Our lactation consultant and Grandmother to many babies told us that the playtex drop ins are the BEST for gas - none of these other ones marketed that way. She says what you do is squeeze the bag and that eliminates a lot of the bubbles. We didn't do this only because we'd already spent so much $ on other bottles. Good luck!
