Query: Finally a Nipple that my Baby Likes

After trying Playtex, Nuk, which both nipples collapsed, and the Avent nipple which was too hard for my 3 month old to suck, a friend suggested Dr. Brown. My baby is unique in that she has cardiac issues. She was able to down these 4 oz bottles in 15 minutes, with minimal gas and no spit-up. It used to take her over 30 minutes to drink previosly mentioned bottles.
