Before I even gave birth to my daughter, I shopped around at all of the bottle feeding options out there. Believe me, I know, there's way too many options and can get quite overwhelming.  Let me assure you that Dr. Brown's baby bottles are the ONLY bottles you will ever need for your child from infancy to toddler. What makes these bottles so unique is the insert within the bottle, which virtually eliminates excess air intake, which in turn causes painful gas for your little one. If you've ever seen or heard a baby with gas, you'll know exactly what I'm talking about -- it's painful for us...
